This study investigates the performance of the circular patch microstrip antenna within-sensing communication systems. A compact patch antenna composed of a circular copper patch layer operated at (2.45 GHz) has been proposed to realize this approach. The circular patch with a radius of 16.80 mm has two etched slots and is placed on a square substrate layer made of epoxy (FR4) dielectric material with dimensions of (67 mm × 67 mm×1.6 mm). The proposed patch antenna design was simulated using CST Studio software, yielding results for performance parameters including return losses, Voltage Standing Wave Ratio (VSWR), bandwidth, and gain. The dimensions of etched slots in the patch layer of the antenna have been tuned to realize the best performance of the proposed antenna. The results indicate a significant enhancement in antenna performance, demonstrated by a return loss of -10.51697 dB, a VSWR of less than 2, and satisfactory gain and bandwidth values suitable for application in diverse communication systems, including efficient medical sensing devices.
