Abstract
A wideband stacked microstrip patch antenna is presented The proposed structure combines the merits of the stacked patch antennas and L-shaped feed for broadband operation. This paper presents extended E and H shaped patch stacked with rectangular patch (53mm X 35mm). The composite effect of integrating inverting techniques and by introducing the proposed patch, offer a low profile, high gain, and compact antenna element. The simulated impedance bandwidth of the proposed antenna is 680 AIM (33%). It is shown that the wide bandwidth is caused by a two-frequency resonance. The study showed maximum achievable gain of about 9.58 dBi and gain variation of 0.76 dBi between the frequency ranges of 1.72GHz to 2.4GHz. Details of the proposed compact and broadband design is presented and discussed in this paper.
