N2 - A ultra-light, compact, high gain 16 × 6 CP antenna array is presented in this paper for Ku band mobile satellite applications. The 96-element array consists of 24 2 × 2 CP sub arrays fed by a substrate-integrated-waveguide (SIW) network. Two essential and innovative techniques were adopted in this design. First, in order to achieve the ultra-light weight, the radiation patches were etched on the Polyimide film supported by a patterned foam. A piece of thin SIW network was designed to feed the radiators. The total weight of the fabricated array prototype is only 66.5 gram and profile is low as 0.05 λ0. Second, a sequential rotation (SQR) feeding technique was applied to the aperture fed 2 × 2 CP sub array, which realized more than three times bandwidth enhancement than the direct (non-SQR) feeding approach. In addition, the measured results show the CP-operational bandwidth is 700 MHz from 11.55 to 12.25 GHz. The peak realized gain is 26.4 dBic and gain variation is stable (less than 3 dB) cross the entire operating bandwidth. Be ultra-light and high gain, it is an excellent candidate for Ku band satellite applications.
