Abstract

This paper proposes three square-aperture horn antennas loaded with grooves in order to shape a circular beam. In a design method for these antennas, the modal coefficients realizing the specified radiation pattern are first determined based on the quadratic programming method. Then the dimension of the horn are optimized so that these modal coefficients can be obtained at the horn aperture plane. The first antenna realizes a circular beam and low cross polarization in the range of 10GHz-10.5GHz by controlling the TE_10 mode and the higher-order TE_12 and TM_12 modes. This horn has a 90◦-rotational symmetry with four grooves. The second antenna realizes the same characteristics in the range of 9.5GHz-10.5GHz by considering the next higher-order TE_30 mode in addition of the before-mentioned three modes. The third antenna realizes the same characteristics in the range of 9.5GHz-11GHz by considering the next higher-order TE_32 and TM_32 mode. Finally, this paper verifies effectiveness of the proposed antennas by measuring their radiation pattern and VSWR
