Abstract

A stacked microstrip patch antenna with 2×2 array structure is being proposed in this paper. The antenna has four (2×2) rectangular radiating patch array on the top of FR4 substrate having air gap with ground plane. A coaxial probe feeding is located along the orthogonal axis of the array. The antenna is simulated using Ansoft HFSS. The designed antenna can excite six operating bands by double U-slot cut on array patch having dimension 43 × 54 mm². The operating bands are centered at 1.64, 1.74, 1.99, 2.30, 2.62 and 2.93 GHz. The return loss, radiation pattern and gain of the proposed antenna are presented.
