A 41% bandwidth microstrip patch antenna

Abstract

This work contains a wideband DS (defected-ground-structure) microstrip patch antenna. Initially, the intention of this work was based on realizing a sub- 6 GHz 5G microstrip patch antenna, but through many experimentations, we inadvertently stumbled upon a different kind of microstrip patch antenna, namely, an antenna with a substantially wide band. The numeric values of the variables/parameters of this compact, wide-band, microstrip patch antenna, that has a proudly high fabrication tolerance, are as follows: S_11 = -10.09 dB, frequency = 8.7 GHz, ε_θ = 2.67 dB, ε_Φ = -2.3 dB. The bandwidth reaches approximately from 6.6 GHz to 10.2 GHz, hence giving this particular design’s bandwidth a proud 41% value.
