Abstract:

Aiming at the application of satellite-borne phased array radar, a low-profile lightweight one-dimensional phased scanning slot array antenna operating in Ku band is proposed. The antenna is based on radio frequenly-digital-power integration design, and system in package (SiP) chips are used to achieve high-density structural integration. Compared with the traditional phased array antennas based on brick or tile transmit/receive (T/R) modules, the proposed antenna design can effectively reduced the height and weight of the antenna profile. The central working frequency of the antenna is 16 GHz, with a working bandwidth of 600 MHz, which can realize one-dimensional beam scanning. In addition, a self-calibration network is designed, which can be used for real-time detection of the amplitude and phase characteristics of the radio frequency channel in orbit. The measurement results of the prototype show that the scanning angle of the antenna can reach ±30°, and the testing result of effective isotropic radiated power (EIRP) and gain-to-noise temperature ratio (G/T) values are consistent with the theoretical calculation values.
