Abstract

A compact metamaterial-loaded wideband monopole antenna is reported in this paper for wireless applications. Initially, a monopole antenna with a single stub was designed to resonate at 4 GHz. Still, it suffers from low gain, so to enhance the antenna parameters, a metamaterial unit cell was considered along the feed line and ground plane. Double split ring resonator (DSRR) is a modified unit cell of a typical split ring resonator (SRR) designed to achieve a good coupling effect. The dimensions of the proposed DSRR unit cell are 0.17λ₀ × 0.17λ₀, where λ₀ is the free space wavelength at 4 GHz. It achieved an impedance bandwidth (-10 dB) in the frequency range of 3.38 GHz to 4.08 GHz & 4.64 GHz to 5.2 GHz, having a 19.49% bandwidth in the 1st band and 11.7% bandwidth in the 2nd band. A wideband was achieved in the frequency range of 3.39 GHz to 5.13 GHz with 47.9% bandwidth when the number of stubs was increased to four. A maximum gain of 3.3 dBi was attained with bidirectional radiation in the E-plane, and it was omnidirectional in the H-plane. By increasing the number of stubs, two resonant modes were merged, making it wideband and suitable for WLAN applications like Wi-Fi & WiMAX & Satellite Communications.
