Design of wideband microstrip antenna with spiral slot on ground plane

Analysis and design of a wideband microstrip antenna is presented in this paper, the antenna size is 25×25 mm
²
and works between frequencies 6.2 GHz to 12.7 GHz which contains the X-band frequency. The HFSS electromagnetic simulation software is used to simulate and analyze the proposed antenna. To show the performance of designed antenna, the radiation pattern and the return loss graphs are presented.
