Abstract

A broadband E-shaped microstrip antenna is proposed in this paper. Its bandwidth is further increased by inserting a pair of tapered slits into an appropriate radiating edge of the rectangular patch antenna. The Antenna is designed and simulated by three-dimensional electromagnetic field software HFSS. Results show that the designed antenna has an impedance bandwidth over 21% (from 12.7GHz to15.7 GHz) for VSWR <; 2, which is four times greater than the conventional rectangular patch antenna. Satisfactory radiation patterns have also been obtained through simulation. The maximum gain in frequency band is 8.52dB. The resulting size of the microstrip antenna is 15 mm×15mm, realizing miniaturization, high power gain, and wide band features of the microstrip antennas.
