High Gain Ultra-Wideband Parabolic Reflector Antenna Design Using Printed LPDA Antenna Feed

Mustafa Pehlivan, Yavuz Asci


Reflector antennas with log periodic dipole array (LPDA) feeds are ideal for applications that demand high gain, broadband operation. However, when the phase center of the LPDA is not fixed, mismatches at the focal point cause degradation and large ripple in gain. To overcome these issues, a printed LPDA is optimized for minimal phase center variation as a reflector antenna feed. The antenna is designed to operate at 1-19 GHz frequency band with voltage standing wave ratio (VSWR) less than 3.0 and minimum gain of 17 dBi. Reflector size can be increased for further improvement in gain. Designed antenna parameters, radiation patterns, and aperture efficiencies over frequencies are presented and compared to previous studies.
