Abstract :
By using inconsistent patch elements in PESPAR (planar electronically steerable passive array radiator) antenna, bandwidth enhancement of this antenna is demonstrated and the relative bandwidth is 5%. Moreover, a new impedance matching method is introduced. Details of the antenna design and results are presented and discussed to validate the performance improvement.
