Comparative Study on Circular and Elliptical Microstrip Patch Antenna Arrays with Microstrip Line and Coaxial Probe Feeding for X-band
A comparative performance study on circular and elliptical shape microstrip patch antennas and their arrays using different feeding techniques at an X band frequency is presented in this paper. The resonant frequency is chosen at 10 GHz which has a variety of application in wireless communication. CST Microwave Studio is used for design and simulation. It is found that microstrip line feeding shows better performance than coaxial probe feeding considering gain and directivity. A 3558.12 mm2 antenna having 2x4 array of circular patch with line feed that gives 16.2 dB gain and 16.4 dB directivity with 94.42% efficiency is the proposed model of this paper.
