In this paper, the authors designed on substrate with dielectric constant 10.2 and thickness of 2.9mm. The size of antenna is compact, patch dimension 17.5x12.3 mm2. The antenna parameters such as return loss, gain and directivity are simulated and optimized using commercial computer simulation technology microwave studio. The return loss is about -28dB, bandwidth is 349MHz, gain is 11.0dB, directivity is 12.4dBi is 1.08 at the operating frequency 3.5GHz.The main advantage of this antenna is that the designed structure is very simple compared to other proposed antennas and the cost for making this antenna is also low.
