Abstract

In this paper, an ultra-miniaturized modified circular printed monopole (MCPM) antenna is proposed for ultra-wideband (UWB) applications. The proposed antenna consists of four circular discs connected to the structure of the MCPM antenna, which leads to enhancing the antenna impedance bandwidth. The stated MCPM antenna is fed by a coplanar waveguide (CPW) to achieve a 50  impedance matching. A Rogers RT5880 substrate (tan  0.0004 and εr  2.2) is employed for design simulation. The proposed UWB MCPM antenna is designed and simulated for frequencies from 3 up to 11 GHz utilizing computer simulation technology (CST) software. The MCPM antenna is successfully designed and simulated, and its parametric study is performed in a comprehensive way to validate the design novelty. Furthermore, the proposed antenna shows a stable radiation pattern with good gain in the operating band. The stated antenna is also compared with the related literature reviews to differentiate its performance. The total dimension of the finalized antenna is 0.150×0.150×0.00160 that corresponds to the lowest operating frequency of 3 GHz. The finalized MCPM antenna achieves peak gain of 3.2 dB and directivity of 3.9 dBi with high efficiency of 85 % at 11 GHz. Besides, the antenna offers a wide enough bandwidth to be used for UWB and radio communication applications.
