Beamforming characteristics of a phased array reflector using a log periodic dipole antenna as an array element

Abstract

This paper proposes bcamforming characteristics of a phased array reflector using a log periodic dipole antenna as an array element. To confirm beamforming capability of the proposed antenna, 4-elements LPDA array are conducted as the feeder of the reflector, and the beamforming capability is observed according to the steering angle. The results demonstrated that the proposed antenna is suitable as phased array-fed reflector antenna for achieving multibeam capability.
