There are various types of antennas that can be used for many applications in communication systems. This paper presents the design and comparison of log periodic antenna and rectangular microstrip patch antenna which are used in satellite application, aircraft and wireless applications such as WiMAX, Wi-Fi, bluettoth, etc. In this paper, the antennas are designed to operate at S band with 2.4 GHz frequency. The antennas are designed with Flame Retardant 4 (FR-4) substrate of thickness 1.6mm with a dielectric constant of approximately 4.4. It is given with coaxial feed and has a partial ground plane. The basic theory and designs are analyzed and simulation can be done by using HFSS software. After simulation, the antenna performance characteristics such as VSWR, return loss and radiation patterns are obtained. From the results of log periodic and microstrip patch antenna, the best antenna is fabricated and then tested practically.
