In this paper, the circular polarized 5.8 GHz patch antenna has successfully designed and simulated. This paper presented a design where both of the opposite edges of the rectangular patch of the antenna are truncated using micro strip feeding technique. Both simulations of the proposed antennas had been analyzed. The objectives of this paper has been achieved which is to design and simulate the circular polarized antenna with operating frequency of 5.8 GHz. From the results, the proposed antennas with different feeding technique that radiate at a constant frequency showed some distinct value towards the size of the antenna and the characteristic of its radiation. The results indicate that the antenna that uses micro strip feed line technique yields 2.337 dB directive gain, return loss and axial ratio at -14.042 dB and 3.193 dB respectivel. Meanwhile, the directivity values for the antennas is 5.31 dBi. It can be conclude that the designed 5.8 GHz antenna is ideal for point to pint communication antenna due to its performances.
