Abstract
In motion slot array antenna for receiving satellite broadcasting is presented. To reduce the loss of feed line and to reduce the coupling between the slots, we use the waveguide feeding network and the circular groove. By using two cross-type polarizers, which are implemented on a single layer film, the proposed antenna can receive RHCP or LHCP by mechanical switching system. The gains of 4x8 and 8x16 slot array antennas are 27.5dB, 31.5dB respectively. Also, in satellite broadcasting band of 11.75~12.75GHz, the axial ratio is smaller than 5dB.
