Summary:
In this paper, a novel dual circular polarization waveguide antenna array with wide band and low axial ratio is presented at X-band. Planar horn array is used to attain dual circular-polarization working with orthomode transducer and rectangular side wall coupler. A demo array of 16×16 elements is designed, manufactured and tested. The experimental results show that the AR is less than 1.5dB, the VSWR is less than 1.5 in the operation frequency band.
