Performance Analysis of Dual Half Circular Overlapped Microstrip Antenna

In this paper a dual overlapped half circular shaped patch with slit antenna design has been proposed. The dimensions of antenna are 29.8 × 25.2 mm
²
and substrate thickness 1.6 mm. The performance analysis of designed antenna considering parameters such as return loss, voltage standing wave ratio, directivity, and radiation pattern has been done using ANSOFT designer HFSS. The antenna has resonating frequencies at (13.44– 14.822) GHz and (16.279- 30) GHz which covers Ku, K and Ka bands. The centre frequency at 14.13 GHz and 23.13 GHz with impedance bandwidth 9.78% and 59.29% and directivity 10.17 dB and 3.6 dB respectively has been achieved in this article.
