The main objective of the paper is to design and implement the microstrip antenna arrays for 2.4 GHz applications. Initially we design and implement single element antenna and analyse outcomes of its features such as operating frequency, return loss, gain, VSWR and radiation patterns. Later the single element is converted to 2x1 patch antenna array. Finally to increase gain, bandwidth and to have better radiation patterns it is transformed to 4x1 patch antenna array. The detailed procedure of design and obtained results of single component, 2x1 microstrip patch antenna array and 4x1 microstrip patch antenna array are discussed. The FR4 substrate material was used in our design and to fabricate the prototype of the antenna. The obtained result of both simulated and measured indicates that they are comparable with one another.
