Abstract
A microstrip antenna with multiple frequency bands is very popular and useful because of its many applications. This research intends to design for triple band and performance analysis of a microstrip antenna by introducing a slotted patch. Efforts are made to maximize the antenna's performance by experimenting with the distance between shorting and feeding pin, slot sizes, and positions, dimensions of the ground plane, and substrate materials. A software named CST is used to produce the results, and the research closes by demonstrating that the slotting patch improves antenna performance. Various patch sizes and substrate materials are initially explored to achieve ideal antenna characteristics. After that, single, double, and more slots designs are included in the patch to improve the antenna performance and also for creating multiband. The developed antenna operates at 9.03 GHz, 10.12 GHz, and 14.3 GHz, and the designed antenna's return losses are -20.33 dB, -33.01 dB, and -13.68 dB respectively. The antenna covers various applications of the X and Ku bands.
