Abstract

HAPS system is required to have strict specification to reduce the interference between adjacent cells. One of the most efficient ways to suppress the grating lobe in visible rang is to shape FTEP (flat-topped element pattern). This work presents the design and experimental results of 7 waveguide dielectric rod array antennas for shaping FTEP in the Ka-band. The calculated element pattern and the measured element pattern are also compared. This prototype antenna will be applied to the multibeam antenna to generate 7 beams using digital beamformer.
