TL;DR: In this paper, a compact Ultrawideband (UWB) high gain microstrip patch antenna using planar metamaterial structures is proposed, which is made by etching π-shaped slot on main radiating patch and crossed shaped slots on the ground plane.
Abstract: In this paper, a compact Ultrawideband (UWB) high gain microstrip patch antenna using planar metamaterial structures is proposed. The antenna has two layers of metamaterial structure which are made by etching π-shaped slot on main radiating patch and crossed shaped slots on the ground plane. The inductances and capacitances developed due to the ground plane and patterned radiating patch leads to the left handed behavior of the metamaterial. The proposed antenna has compact size 27.6×30.8mm2 with height 1.6mm and designed on low cost FR4 substrate. The impedance bandwidth (−10dB) of the antenna is 3–12GHz with average gain of 4dBi and the peak gain 5.8 dBi at 9.5 GHz. The results obtained from the simulation studies shows that the antenna has good radiation characteristics for the UWB applications.

TL;DR: In this paper, a size reduction technique of the microstrip patch antenna using metamaterial has been proposed, which shows significant reduction in the antenna size for the specific resonance frequency of operation.
Abstract: A size reduction technique of the microstrip patch antenna using metamaterial has been proposed. In order to establish that, inset-fed microstrip patch antenna working with L-S band (2 GHz – 5 GHz) is optimized through the available closed form relations and CST (computer simulation technology) simulator, fabricated and measured. Then proposed microstrip patch antenna has been loaded with complementary split-ring resonator (CSRR) at the ground plane, fabricated and measured. Performance of both the antenna was compared with respect to reflection coefficient, in order to prove the miniaturization. Beforehand, a metamaterial property of the CSRR loaded substrate is verified using transmission line model. Proposed method shows significant reduction in the antenna size for the specific resonance frequency of operation.

TL;DR: In this article, an effort has been made to use the metamaterial structure in union with the Sierpinski fractal pedal antenna, which resonates at six different frequencies covering C, X, K and Ka bands.
Abstract: In this paper, an effort has been made to use the metamaterial structure in union with the Sierpinski fractal pedal antenna, which resonates at six different frequencies covering C, X, K and Ka bands. It is designed and simulated using Ansoft HFSS which is proposed for SHF (Super High Frequency) applications. Metamaterial used in design increases gain and efficiency of antenna systems, as 90 percent of the input signal is reflected back to the antenna design and Sierpinski fractal antenna provides multiband and high frequency. Antenna is etched on an FR4 epoxy substrate whose dielectric constant is 4.4. It radiates at 10 GHz, 21.7GHz, 24.5GHz, 25.8GHz and 29.6 GHz covering wide range of applications. The overall size of an antenna is 35 × 52 × 1.57 mm3.

Abstract: This paper presents a study of a novel monopole antenna for ultrawide-band (UWB) applications. Printed on a dielectric substrate and fed by a 50 /spl Omega/ microstrip line, a planar circular disc monopole has been demonstrated to provide an ultra wide 10 dB return loss bandwidth with satisfactory radiation properties. The parameters which affect the performance of the antenna in terms of its frequency domain characteristics are investigated. A good agreement is achieved between the simulation and the experiment. In addition, the time domain performance of the proposed antenna is also evaluated in simulations.

TL;DR: In this paper, a microstrip-line-fed printed wide-slot antenna with a fractal-shaped slot for bandwidth enhancement is proposed and experimentally studied, and it is experimentally found that the operating bandwidth can be significantly enhanced, and the relation between the bandwidth and the iteration order (IO) and iteration factor (IF) of the fractal shapes is investigated.
Abstract: Microstrip-line-fed printed wide-slot antenna with a fractal-shaped slot for bandwidth enhancement is proposed and experimentally studied. By etching the wide slot as fractal shapes, it is experimentally found that the operating bandwidth can be significantly enhanced, and the relation between the bandwidth and the iteration order (IO) and iteration factor (IF) of the fractal shapes is experimentally studied. Experimental results indicate that the impedance bandwidth, defined by - 10 dB reflection coefficient, of the proposed fractal slot antenna can reach an operating bandwidth of 2.4 GHz at operating frequencies around 4 GHz, which is about 3.5 times that of a conventional microstrip-line-fed printed wide-slot antenna. It also achieved a 2-dB gain bandwidth of at least 1.59 GHz.

TL;DR: In this article, a broad bandwidth and high gain rectangular patch antenna was designed using planar-patterned metamaterial concepts, which has isolated triangle gaps and crossed strip-line gaps etched on the metal patch and ground plane, respectively.
Abstract: A broad bandwidth and high gain rectangular patch antenna was specifically designed in this paper using planar-patterned metamaterial concepts. Based on an ordinary patch antenna, the antenna has isolated triangle gaps and crossed strip-line gaps etched on the metal patch and ground plane, respectively. Demonstrated to have left-handed characteristics, the patterned metal patch and finite ground plane form a coupled capacitive-inductive circuit of negative index metamaterial. It is shown to have great impact on the antenna performance enhancement in terms of the bandwidth significantly broadened from a few hundred megahertz to a few gigahertz, and also in terms of high efficiency, low loss, and low voltage standing wave ratio. Experimental data show a reasonably good agreement between the simulation and measured results. This antenna has strong radiation in the horizontal direction for some specific applications within the entire band.
