홈페이지논문 초록 (Abstract)
A feed horn antenna including circular-polarizer and straight type mode converter for a phased array is proposed to illuminate a shaped reflector antenna and be extended to an array of 8×1. The proposed antenna has a very good radiation pattern and wide axial ratio bandwidth compared to the microstrip elements. In additional to that, if we replace the dielectric type polarizer with oval shape waveguide, insertion loss is reduced.
