Mono pulse tracking systems are mostly used in target-tracking applications. In general, the antenna of a mono pulse tracking system is divided into four quadrants, and the inputs of this antenna are combined using a sum and difference network, to give horizontal and vertical sum and difference signals. According to the convention, the sum and difference signals of a tracking system are obtained by the sum and difference feeding network. This network is often composed of four magic tees combined with two tees, whose arms are located in four different directions, which occupy a large volume. In this article, an eight-port feeding network is proposed instead of four four-port magic tees. The eight - port feeding network in the X - band is analyzed by the full-wave method and has phase stability and suitable power between the ports. The proposed structure is used in the feeding network of monopulse radars.
