Abstract

A novel compact differential microstrip antenna is presented. Owing to the introduction of slots in the patch and ground plane, the size of the proposed differential antenna is about 0.45 times that of the traditional microstrip antennas. The measured results show that the proposed antenna can work at 2.45 GHz. The gain is about 5.54 dB and the impedance bandwidth about 150 MHz.
