A micro strip patch array antenna on two different dielectric substrates namely RT Duroid 5880 having dielectric constant 2.2 and Ceramic poly-tetra-fluoro-ethylene (PTFE) having dielectric constant 2.9 have been designed and simulated at 5.8 GHz frequency. “Computer Simulation Technology Microwave Studio Software (CST MWS)” package has been used for simulation. 2X8 patch array antenna is designed, simulated and fabricated on RT Duroid 5880 substrate. The simulated parameters are - reflection coefficient (S11) -15 dB at 5.56 GHz. The gain of the antenna is 17.5 dBi and the azimuth and elevation 3dB beam width is around 8.6° and 30° respectively. The fabricated antenna results show the reflection coefficient of - 21.1dB at 5.88GHz with 160 MHz bandwidth. The differences are attributed to the tolerances in the fabrication process and/or the substrate and connector characteristics. 2X8 patch array antenna has been simulated on PTFE substrate. The reflection coefficient (S11) is -21 dB at 5.8 GHz, gain is ~15 dB and the 3dB beam width for azimuth and elevation is 11° and 34.5° respectively. In order to improve the gain and azimuth and elevation beam widths of antenna 4X8 patch array antenna has been simulated on ceramic PTFE substrate. The simulated reflection coefficient is -30dB at 5.8 GHz frequency and the simulated gain is ~ 17dB the 3db beam width for azimuth and elevation is 11°and 25°respectively. The required frequency 5.8 GHz of fabricated antenna (RT Duroid 5880) is achieved by using stub matching inside the feed network. This also provides a band width improvement.
