Abstract
A compact metastructure (MTS) antenna utilizing zeroth order resonance (ZOR) techniques has been reported in this paper. The proposed coplanar waveguide (CPW) based MTS antenna has made up of interdigital capacitor (IDC), split ring resonator (SRR) and strips (rectangular and U-shaped). ZOR is a magnificent technique by which small dimensions of the antenna is attained. The presented structure exhibits compact size of 0.24λ0 × 0.27λ0 × 0.024λ0, where λ0 is the free space wavelength at ZOR frequency of 4.61 GHz. In the presented paper ZOR frequency is configured by series LC parameters as it follows short-ended boundary condition. The U-shaped strip is basically used to provide capacitance with the SRR which affects the resonance frequency by controlling the series inductance and capacitance of proposed short-ended structure. It is noticed that the presented antenna exhibits working band operation at 4.61 GHz (4.16–4.8 GHz) with input reflection coefficient of − 50.32 dB at ZOR frequency. The proposed antenna achieves properties such as omni-directional and dipolar radiation pattern in xz-plane and yz-plane respectively. Measured peak gain of 2.52 dB and simulated radiation efficiency of 94.27% permits the MTS antenna to be used widely in C-band applications. The designed antenna is fabricated and experimentally verified.
