摘要：

A Novel Semi-Symmetric curvature slot impregnated Decagonal shaped microstrip patch antenna with miniaturized dimensions of 20 x 12 mm2 has been designed and analysed for its working in the frequency range of 4.56 to 12.42 GHz. This paper focuses more on how geometrical changes in the slots affects the impedance, radiation pattern, gain and polarization of the microstrip patch antenna with Defected Ground Structure (DGS). The emphasis is on achieving adequate antenna impedance matching with the help of a nonlinear, semi-symmetric curvature slot to improve the peak gain and to achieve circular polarization. Despite being a single element with wideband characteristics, an average peak gain of 12.96 dB has been recorded for the operating bandwidth of 7.86 GHz. Simulated and measured results of the proposed antenna are analysed w.r.t the Return Loss characteristics pertaining under -10 dB © 2021 School of Science, IHU. All rights reserved
