Abstract A novel broadband microstrip antenna is presented. Double patch configuration is employed, and a circular metal is introduced on the top of the feed probe to counteract the inductance of the probe. As a result, the bandwidth of microstrip antenna is increased. Broadband microstrip antennas suitable for second generation and third generation mobile communication are fabricated, whose measurement results show that good bandwith characteristics are obtained, which can address the need of bandwidth for the mobile communication system.
