Analysis and Design of Capacitive Coupled Wideband Microstrip Antenna in C and X Band
In this paper, design and analysis of capacitive fed wideband microstrip antenna suspended above the ground plane is presented. It is demonstrated that the proposed antenna can be used for wideband application with impedance bandwidth of about 51.13% at center frequency 7.255GHz with a good gain in various microwave bands (C and X band). This antenna has utilized the concept of capacitive coupling for bandwidth enhancement. Suspension of structure above ground plane has also been utilized for the enhancement of bandwidth.
