The paper considers dual-band antenna arrays of satellite television systems. The advantages and disadvantages of such antennas are noted in comparison with widely used mirror antennas. The design of a dual-band microstrip radiator has been developed. Parametric optimization of the radiator has been carried out in order to improve the frequency characteristics of matching. The models for calculating individual elements and arrays consisting of broadband microstrip radiators have been developed using modern software packages for calculation of antennas and microwave devices. The directivity characteristics and frequency characteristics of the emitters of the microstrip antenna array operating in the reception and transmission modes have been determined. The possibility of joint independent operation of the transmitting and receiving channels of the antenna array due to polarization decoupling has been shown. The directional characteristics of the microstrip antenna array operating in the receiving and transmission mode have been determined.
