Abstract

A wideband rectangular patch antenna is presented and experimentally investigated in this paper to covering X- and Ku-Bands. The results are given in terms of the reflection coefficient, and the radiation pattern, and the realized gain. The simulated and experimental results are in agreement. The measured result shows that the wideband antenna works around two resonant frequencies of 11.073 GHz and 14.927 GHz and can cover a spectrum of 6.727 GHz between 9.011 GHz and 15.738 GHz (for return loss under -10 dB). The radiating patch of the antenna occupies an area of 9 × 6.5 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and printed on FR-4 epoxy substrate. The overall size of the proposed antenna with a half printed ground plane is 15.5 × 10 × 1.6 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> .
