Received: 28 December 2019 Accepted: 3 February 2020 A compact wide-band planar antenna is proposed using the metamaterial transmission line. The motivation of this study is to overcome the problem of low bandwidth while designing a miniaturized antenna. The proposed design consists of a rectangular patch and a squareshaped split-ring resonator (SSSRR) on the asymmetric ground plane. Strip lines are provided to connect the right ground plane to obtain the shunt inductances and improve the bandwidth. This antenna has a miniature physical size of 20×28×1.6 mm corresponding to the electrical size of 0.16λo × 0.23λo × 0.013λo, where λo is the free space wavelength at the resonant frequency 2.51 GHz. The obtained results show that this antenna has wide-band from 2.2 GHz to 12.63 GHz, which makes it a good candidate for cover various standards of WLAN (2.4/5.2/5.8 GHz), WiMAX (2.5/3.5/5.5 GHz), satellite TV (7.14 GHz), and X-band (10.19/ 12.02 GHz). The proposed antenna simulations and analyses were performed using the CST simulator.
