Abstract

In this paper, we investigated and proposed a design of backfire microstrip patch antenna with improved bandwidth and return loss. The proposed antenna was designed and fabricated with given set of parameters with suitable design equations and method of movement approach. The simulated result shows that bandwidth is around 37.5 %, return losses is approximately −45 dB, VSWR < 1.5 and directivity is 8 dBi. The hardware fabrication and testing is also performed and validation results are close to simulated results. The proposed antenna is suitable for S and C band.
