TL;DR: In this article, a dual band E-shaped patch antenna for UWB applications is presented, which uses foam of 5mm thickness as substrate, resonates at 5.3 GHz and 7.4 GHz with impedance bandwidth of 760.43 MHz and 1.39 GHz respectively.
Abstract: This paper presents the design and study of a dual band E-shaped patch antenna for UWB application. The antenna uses foam of 5mm thickness as substrate, resonates at 5.3GHz and 7.4 GHz with impedance bandwidth of 760.43 MHz and 1.39 GHz respectively. Better impedance bandwidth of 2.75 GHz (45%) is obtained by incorporating slots in the ground plane. Diversity structure is also realized. The antenna can be used for high speed (IEEE 802.11a) wireless computer local area network (WLAN) and other wireless application.

TL;DR: In this article, a compact UWB printed monopole antenna design is proposed, which has the form of an E-shaped structure printed on a substrate with relative dielectric constant of 3.38 and thickness of 1.52mm.
Abstract: In this paper, a compact UWB printed monopole antenna design is proposed. The monopole antenna has the form of an E-shaped structure printed on a substrate with relative dielectric constant of 3.38, and thickness of 1.52mm. The matching through the UWB response is satisfled using a reduced ground plane. The proposed antenna is fed by a 50› unsymmetrical microstrip line. The ground plane is printed beneath the microstrip line. Modeling and perfor- mance evaluation of the proposed antenna have been carried out using the commercially available electromagnetic simulator, IE3D from Zeland Software Inc. A parametric study is performed to show the efiects of the difierent antenna parameters on the overall antenna performance. The performance of the antenna is mainly afiected by geometrical and electrical parameters, such as the width and length of the branches of the E-shape structure, feed gap as well as the ground plane. Simulation results show that the proposed antenna possesses an operating bandwidth, for return loss • i10dB, extending from approximately 2.93GHz to about 14GHz which covers the entire UWB band of 3.1GHz to 10.6GHz.

TL;DR: In this article, an E-shaped printed slot antenna is presented as a candidate to cover dualband operation over the entire wireless local area network (WLAN) frequency bands of 2.4-2.5 GHz and 4.9-5.8 GHz.
Abstract: An E-shaped printed slot antenna is presented as a candidate to cover dualband operation over the entire wireless local area network (WLAN) frequency bands of 2.4–2.5GHz and 4.9–5.8 GHz. The E-shaped slot structure has been etched in the ground plane, and the 50 microstrip line feed is etched on the reverse side of the substrate. An additional trapezoidal slot has been etched attached to the slot structure on the feeding side to facilitate tuning and the dual-band operation. The antenna structure has been modeled and its performance has been evaluated using a method of moment based electromagnetic simulator, IE3D from Zeland Software Inc. Simulation results show that, the proposed antenna offers good return loss response (for S11 less than −10 dB) at the two bands. The ratio of the two resonating frequencies f02/f01 could be varied in a considerable range, without changing the antenna external dimensions, making the antenna suitable for other dual band wireless applications.

TL;DR: In this article, a dual-band modified E-shaped antenna is proposed for wireless application, in which the stub structure is added into the E-shape patch antenna to achieve the 2.4/5.8GHz dualband performance, the effects of several fundamental design parameters of the novel antenna structure on reflection coefficient are investigated.
Abstract: In this paper, a novel dual-band modified E-shaped antenna is proposed for wireless application. In order to achieve the 2.4/5.8GHz dual-band performance, the stub structure is added into the E-shaped patch antenna. The effects of several fundamental design parameters of the novel antenna structure on reflection coefficient are investigated. It is found that the two operating bands of the proposed antenna can be obtained by choosing proper design parameters of the novel E-shaped patch. In addition, a dual-band electromagnetic-band gap (EBG) structure is applied to improve radiation performance.

TL;DR: The primary goal of this work is to design antenna with smallest possible size and better polarization that covers all the high speed WLAN standards ranging from 4.90 GHz to 5.82 GHz.
Abstract: Allocation of frequency spectrum for Wireless LAN is different in different countries. This presents a myriad of exciting opportunities and challenges for design in the communications arena, including antenna design. The high speed WLAN has many standards and most antennas available do not cover all the standards. The primary goal of this work is to design antenna with smallest possible size and better polarization that covers all the high speed WLAN standards ranging from 4.90 GHz to 5.82 GHz. General Terms Antenna design, WLAN, Microstrip.

TL;DR: In this paper, a full-wave spectral domain analysis has been used to obtain input-impedance results for a probe-fed rectangular-patch antenna, modeling the source as a magnetic current frill.
Abstract: A full-wave spectral domain analysis has been used to obtain input-impedance results for a probe-fed rectangular-patch antenna, modeling the source as a magnetic-current frill. Multiple modes are used in the probe surface current to account for axial and azimuthal variations. It is established that maximum resistance is dependent on the substrate loss tangent. The axial variation of the probe current must be taken into account for substrate thicknesses greater than about 0.02 wavelengths.

Abstract: This article presents the design simulation, fabrication and measured performance of a 2.4 GHz polarization-diversity printed dipole antenna for wireless communication applications. Two orthogonal printed dipole antennas, each with a microstrip via-hole balun for vertical and horizontal polarization, an combined and fabricated on a PCB substrate. PIN diodes are used as switches to select the desired antenna polarization. The 3D finite-element-method (FEM) electromagnetic EM simulator, HFSS, is used in the design simulation of this planar antenna structure. Numerical and measured results of the antenna radiation characteristics, including input SWR, radiation pattern coverage and polarization-diversity, are presented and compared.

Abstract: Several probe-fed L-shaped microstrip patch antennas, which are targeted at wireless computer networks and other similar systems operating in the 5.0-6.0 GHz frequency range are presented. The gap between the patch and the ground plane is filled by foam or air. The effect of the height of the antenna and the size of the ground plane on the antenna bandwidth is investigated. Both theoretical and experimental results demonstrate that the required bandwidth can be achieved with a height of about 3.5 mm.
