A wideband metamaterial antenna employing SRR loading is presented. Two designs were simulated, fabricated and measured. The bandwidth enhancement is achieved by loading SRR resonator onto a conventional monopole antenna. The SRR excited a lower resonance frequency mode which matches with the resonance frequency of the monopole antenna thereby extending the overall impedance bandwidth from 26% to...
This paper presents a compact 3-dB coupler on a dual substrate layer with a rectangular slotted microstrip ground plane. The coupler is designed for operating frequency at 2.45 GHz using an inexpensive FR-4 substrate. A compact coupler design with dimension of 19 mm × 7.5 mm offers a size reduction of 62 % while simultaneously enhanced the bandwidth to 42.7 % compared to a conventional coupler.
In this paper, an array of series fed antenna based on tapering patch width and through element is presented. The antenna has wide impedance bandwidth of 16.18% covering from 5.34 GHz to 6.28 GHz with a gain of 6.53 dBi. The use of through element technique reduces the overall length of array structure by 25.47%. It also has lower side lobe level, and wider impedance bandwidth compared to the past...
