Microstrip patch antennas are versatile in terms of their geometrical shapes and implementation. The light weight construction and the suitability for integration with microwave integrated circuits are two more of their numerous advantages. Additionally the simplicity of the structures makes this type of antennas suitable for low-cost manufacturing. And this is also one key feature why microstrip patch antennas are used in mobile communication applications. Inhibiting characteristics of a single microstrip patch, like low gain and smaller bandwidth, make it more necessary for array configuration. In this paper, the design and simulation of microstrip patch antenna array was done. The design involved 1- patch, 4 x 1 liner arrays, with an element spacing of a half of a free space wavelength.
