Abstract
A new H-shaped feed-network for CP-PASS (circularly polarised printed array composed of strip dipoles and slots) is presented which allows a wider axial-ratio bandwidth to be realised at 12 GHz band. By using the H-shaped feed-network, a 12*2 element-set CP-PASS gives a 3 dB axial-ratio bandwidth of 6%.
