摘要：
This paper represents a new active phase array antenna for Ku-band mobile service that will be possible in satellite broadcasting service. The main idea for the antenna is to use minimum active array element with cost-effective one-dimensional subarrays with inclined pencil beam structure for 34 dBi gain. For this antenna, we also used the squint beam tracking algorithm. This tracking gives different way to the traditional monopulse tracking method in tracking capability. Electronic scanning angle of beam peak in this antenna is over +/-12 degrees wide only with 20 phase shifter elements for its scan ranges. This antenna with the attractive hybrid-tracking concept has about 142 times less array element than antennas with two-dimensional array.
