Abstract

The demand for low cost and less weight antenna with compact broadband features in communication system is rapidly increasing. In this work, the possibility of employing dual gap on square patch reflectarray antenna for bandwidth improvement is presented. The introduction of dual gap attached on square patch is shown to improve the bandwidth performance from 315 MHz to 397 MHz. Moreover 26% improvement of bandwidth performance offers an achievable static reflection loss of 0.28 dB. Several parameters of reflectarray antenna such as reflection loss, reflection phase, bandwidth and figure of merit (FoM) are also discussed in this work.
