Abstract
This paper describes the effect of integrated artificial magnetic conductor (AMC) loaded circular shaped microstrip patch array antenna on its gain and bandwidth enhancement. The proposed antenna prototype operates on 2.45 GHz. Initially a circular 2x2 array antenna is designed which shows bandwidth of 100 MHz and gain of 13.3 dB. Thereafter, AMC loaded superstrate is incorporated into each circular radiating patch resulting in the enhancement of bandwidth and gain up to 30% and 20% as compared to the previous design prototype. Comparatively better return loss (S11) is also achieved due to AMC introduction. The proposed antenna is designed using CST Microwave Studio 2018.
