Abstract: The paper details test of Dual Polarized Parabolic Dish Antenna, at centre frequency of 3GHz, around 100HPBW in azimuth, elevation planes and LPDA (Log Periodic Dipolar Antenna) has feed. The antenna has ability to switch peak power of 1.5KW over a bandwidth of 50GHz and also be able to withstand the environmental conditions like wind, rain. The investigations which have taken place previously have concluded that the prime focus Parabolic Antenna is the most apparent one to meet the design requirement. The LPDA is dependent on operational frequency and is at a focal point of 0.25m to the parabolic reflector of 0.6m diameter. Investigations on the Parabolic Antenna contain gain, VSWR, Half Power Beam Width in both planes of the antenna. The Parabolic Dish Antenna with LPDA feed has been found with 8.560 and 10.50 HPBW of both azimuth and elevation respectively. The gains at different frequencies are comparable with the theoretical values. The antenna fabricated is tested and is in compact size to meet all the requirements of power, bandwidth. Finally, the results are shown with the antenna meeting all the requirements and ready for practical use.
