Microstrip patch antenna arrays are very popular in present wireless communication system, especially when the signal propagates through different fading environment. It is very important to design compact communication tool to fulfill multi-purpose demands of communication world. In this paper, a double layered 2-element, slotted patch antenna array structure is proposed. It is designed to function in 1.8GHz, 2.45GHz and 3.0GHz bands. This is achieved by using additional slots to the lower rectangular patch of dimension 6.8cm by 5.5cm and upper patch of dimension 4.8 cm by 4.0 cm.
