Abstract
In this paper, we describe the design, manufacture, and performance test results of a highly integrated tile-type Rx phased-array antenna for Ku-band satellite communication. The designed tile-type receive phased-array antenna is composed of three multilayer boards. The first board consists of 8×8 arrayed patch antennas and a core chip with a low-noise amplifier and phase shifters. The second board includes a true time delay(TTD) circuit to minimize the beam squint in the wide frequency band and amplifiers. The third board consists of circuits to control the phase shifters and TTD circuit in boards 1 and 2, respectively. The manufactured tile-type antenna has the size and weight of 33×96×96 mm3 and 250 g, respectively. The results of the electrical performance test of the antenna are that the antenna gain and beam width are 24 dBi and 12° at the center of the operating frequency in the Ku-band. Further, the beam squint performance is less than 1° when steering through 0° and 40° in the ϕ and θ directions, respectively. A conformal phased-array antenna can be produced for satellite communication in the Ku-band using the proposed tile antenna.
