Abstract: A design of sum and difference feeding network has been disigned in this paper ,which consists of twenty sixhybrid tee,Waveguide magic T and connection component .Small size has been received from using slot-coupling form . Thenetwork is simulated in HFSS ,the vswr of input waveport is less than 1.14 . The results of the network been simulated withantenna indicate the network is perfect for practical utility.
