Due to the integration of different wireless applications at different bands on a single device, multi-band microstrip patch antenna is the best solution keeping the overall size of the device small. In the present work, a metamaterial-inspired antenna is proposed for WiMAX/WLAN applications. Design studies, parametric analysis, simulation results along with measurements for a L-shape slotted g...

A proximity-fed annular slot antenna for UWB applications with a band rejection using different techniques is presented. The proposed antenna provides an UWB performance in the frequency range of ≈ 2.84 to ≈ 8.2 GHz with relatively stable radiation parameters. Three different techniques to construct a resonant circuit for the proposed antenna are investigated to achieve the band-notch property ...

In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...

A nondestructive complementary split ring resonator (CSRR), working in the 0.5 to 6 GHz frequency range, is presented this work. Three CSRR designs, on same 5 mm by footprint, with different internal dimensions were designed, fabricated, and measured. The results demonstrate a large shift resonant frequency, up 2.544 GHz, over broad relative permittivity range from 1 80, penetration depth, 7 mm...

In this paper, a symmetrical monolayer metamaterial superstrate is placed on microstrip patch antenna resonant at 3.5 GHz. MTM based CSRR Complementary Split Ring Resonators, constituting two rectangular rings opposite splits both ends, which are printed Rogers RT 5880 type substrate with relative permittivity of 2.2, tangential loss 0.0009, and thickness 0.508mm. This resonator capable exhibit...

In this article, a novel and compact ultra-wideband (UWB) planar antenna is presented. This antenna consists of an annular patch and a 50 microstrip feed line. The 3.5/5.5GHz dual band-notched characteristic gets achieved by etching a C-shaped slot in the patch and complimentary split ring resonator (CSRR) structure in the ground. The measured results show that the proposed antenna can achieve ...
