Rapid progress in wireless communication promises to replace wired communication networks in the near future in which antennas play a more important role. MicroStrip Antennas (MSAs) are used in a broad range of applications from communication systems to biomedical systems, primarily due to several attractive properties such as light weight, low profile, low production cost, conformability, reproducibility, reliability, and ease in fabrication and integration with solid state devices. This paper is aimed to investigate microstrip patch antenna for WIFI (i.e. 2.4 GHz frequency range) application. For this purpose there are two model of microstrip patch antenna which has been presented. The antenna characteristics such as return loss, radiation pattern, bandwidth and smith chart are considered for performance evaluation.
