TL;DR: The obtained bandwidth and radiation characteristics make the double G antenna proper to be used for WiFi and 4G LTE applications in the 2.4GHz to 2.7GHz band and 5.1GHz to 5.875GHz band.
Abstract: In this paper, a “double G” textile CPW-fed monopole antenna design for dual-band WLAN applications is proposed. Return loss, realized gain and radiation patterns measurements are used to characterize a manufactured prototype. The obtained bandwidth and radiation characteristics make the double G antenna proper to be used for WiFi and 4G LTE applications in the 2.4GHz to 2.7GHz band and 5.1GHz to 5.875GHz band. Moreover, effects on the return loss for the novel design antenna under bent conditions are further discussed.

TL;DR: In this paper, the authors proposed a method that enables to extract antenna efficiency estimation from reverberation chamber measurements and more specifically from the composite Q-factor estimation of the reverberation chambers.
Abstract: This communication deals with a method that enables to extract antenna efficiency estimation from reverberation chamber measurements and more specifically from the composite Q-factor estimation of the reverberation chamber. It is another variant of antenna efficiency measurement method in a reverberation chamber that takes advantage of the properties of the composite Q-factor that involves various components including the quality factor of antennas themselves. We show that in a well-overmoded cavity, the Q-factor measured from two antennas in the chamber gives access to the contrast of their efficiency. Estimation uncertainty is discussed with regard to the substitution method.

Abstract: This letter presents a circuit model to design a double-layer square artificial magnetic conductor (AMC) with a small period relative to the wavelength in the UHF band. The miniaturization is achieved thanks to a square patch array printed alternatively on each side of a thin dielectric substrate. These closely spaced arrays cause a high grid impedance allowing to decrease the period of the AMC. The proposed model is validated by simulations for several configurations and by measurements. The resonance frequency of the realized AMC is 2.68 GHz with a bandwidth of 260 MHz. The dimensions of the unit cell are $ 11.5 \times 11.5~\hbox{mm}^2$ or $0.1{\lambda _0} \times 0.1{\lambda _0}$ .

TL;DR: In this article, a bendable artificial magnetic conductor (AMC) with a resonant frequency of 400 MHz was proposed and the dimensions of the unit cell were 50 × 50mm2 or 0.07 λ0.07
Abstract: A bendable artificial magnetic conductor (AMC) with a resonant frequency of 400 MHz is proposed. The dimensions of the unit cell are 50 × 50 mm2 or 0.07 × 0.07 λ0. The miniaturization is achieved with closely coupled patches printed on each side of a 0.127-mm-thick dielectric substrate. This last one is stacked on a flexible 3-mm-thick silicone over a ground plane. An AMC prototype is simulated and manufactured. Also, a printed inverted-F antenna is used to highlight the bandwidth of the AMC.

TL;DR: In this paper, a dual-band wearable textile antenna based on substrate integrated waveguide technology is presented for operation in the [2.4-2.4835]-GHz Industrial, Scientific and Medical band and the [ 2.5-1.69]-GHz 4G LTE band 7.
Abstract: A dual-band wearable textile antenna based on substrate integrated waveguide technology is presented for operation in the [2.4-2.4835]-GHz Industrial, Scientific and Medical band and the [2.5-2.69]-GHz 4G LTE band 7. The antenna features an integrated flexible solar harvesting system, consisting of a flexible solar cell, a power management system, and energy storage. All these components are judiciously positioned on the antenna platform in order not to affect its radiation performance. The measured reflection coefficients and radiation characteristics after bending and deploying the antenna on a human body prove that the antenna is well suited for on-body use. A measured on-body antenna gain and radiation efficiency of 5.0 dBi and 89% are realized. Measurements in a real-life situation have demonstrated the ability to scavenge a maximum of 53 mW by means of a single integrated flexible solar cell.

TL;DR: In this article, a broadband and a dual-band printed slot antennas for future millimeter wave mobile network communication are proposed for the Ka-band frequency of operation, where the basic antenna design consists of a circular radiating patch that is placed non-concentrically inside a circular slot etched off the ground plane.
Abstract: In this paper, a broadband and a dual-band printed slot antennas for the future millimeter wave mobile network communication are proposed. The antennas are designed for Ka -band frequency of operation. The basic antenna design consists of a circular radiating patch that is placed non-concentrically inside a circular slot etched off the ground plane. Matching between a radiating patch and the 50 Ω microstrip line is manipulated through a proximity-feed technique. The simulated antenna prototype – I and prototype – II are fabricated and successfully measured. The results indicate that the proposed antenna prototype – I yields the broadband impedance bandwidth >20 GHz (from 20 to >40 GHz) define by S 11

TL;DR: In this paper, a dual-polarized dipole antenna topology with a broadband multilayer Artificial Magnetic Conductor (AMC) based reflecting surface is presented. But the antenna structure is not suitable for interoperable Long Term Evolution (LTE), Code Division Multiple Access (CDMA) and Global System for mobile communications (GSM) applications.
Abstract: The paper presents a low profile dual polarized dipole antenna topology backed by a novel broadband multilayer Artificial Magnetic Conductor (AMC) based reflecting surface. The antenna consists of a pair of square loop shaped dipoles with T-shaped feed structures arranged orthogonally to provide dual slant polarizations at ±45°. The antenna structure is backed by a novel multilayered AMC structure consisting of stacked square patches with via connected at middle and an air filled ground plane at the bottom. Experimental results show that the proposed antenna operates from 700 to 1000 MHz with bandwidth of 35% and an average gain of 8.5 dBi over the bandwidth. The Simulated and measured results of the antenna structure indicate the antenna to be suitable for interoperable Long Term Evolution (LTE), Code Division Multiple Access (CDMA) and Global System for mobile communications (GSM) applications.

TL;DR: In this paper, a modified H-shaped double negative (DNG) metamaterial unit cell aimed at X and Ku-band applications has been presented, which achieved a multiband DNG bandwidth of 0.845 GHz (7.615-8.46 GHz), 0.605 GHz (8.755-9.36 GHz), and 4.32 GHz (10.68-15 GHz).
Abstract: A modified H-shaped double negative (DNG) metamaterial unit cell aimed at X- and Ku-band applications has been presented. Combination of rectangular split ring resonator and complementary H-shaped resonator has been used to construct the unit cell. A multiband DNG bandwidth of 0.845 GHz (7.615–8.46 GHz), 0.605 GHz in X band (8.755–9.36 GHz), and 4.32 GHz in Ku-band (10.68–15 GHz) has been achieved by the unit cell. Moreover, the unit cell has realized a compact size of 0.792 cm2, which is the smallest reported size with the DNG bandwidth more than 4 GHz in a particular band. Commercially available finite difference time domain (FDTD)-based computer simulation technology (CST) has been used for designing the unit cell. Effect of different parts of the unit cell on resonance characteristics has also been alluded. Different array structures have been designed and analyzed for the verification of DNG characteristics. 4 × 4 array has been fabricated which shows close likelihood with the simulated results. Simulated and measured results confirm the effectual involvement in X- and Ku-band applications.

TL;DR: In this article, a saber-like antenna with low wind drag is proposed for on-board communication application, under the requirements of polarization diversity and omnidirectional coverage.
Abstract: In this communication, a compact saber-like antenna with low wind drag is proposed for on-board communication application, under the requirements of polarization diversity and omnidirectional coverage. The proposed antenna consists of a thin resonant cavity for omnidirectional horizontal polarization (HP), and a folded slot is colocated with the cavity to provide omnidirectional vertical polarization (VP). Isolation lower than −20 dB between two feeding ports is achieved in a quite compact dimension of $30 \times 29 \times 9$ mm3( $0.24\lambda _{0} \times 0.24\lambda _{0} \times 0.07\lambda _{0}$ , $\lambda _{0}$ is the free-space wavelength at 2.44 GHz), also with the omnidirectional patterns for both polarizations. A prototype of the proposed antenna is fabricated and tested to verify the design strategy. Compared with previous designs, the cross section area for wind drag is reduced for more than 28.5%, exhibiting potential usage for high-speed moving antenna carriers.
