A Novel Compact and Broad Band Microstrip Patch Antenna

A novel method of designing broadband microstrip antenna is proposed in this paper. By embedding cross-shaped slots placed close to the non-radiating edges, it is tested for two conditions- one with the addition of cross shaped slot at the centre and another with the addition of swastika shaped slot at the centre. The analysis is performed which indicates antenna 2 superior to Antenna 1 over both the bands viz. 3.5 GHz and 4.2 GHz. The measured broad band is achieved with small sizes, and good radiation characteristic is also observed for operating frequencies within the impedance bandwidth.
