Abstract

This paper presents design of mono pulse comparator. The main aim of this comparator is for tracking applications, in this comparator total 8 ports in that 4 ports are input and another four ports are out put ports, in that output ports one is sum port and two ports difference ports, one termination port, in that two difference ports one is azimuth difference and elevation difference, ratio of difference (azimuth or elevation), sum will give the bore sight error. And this comparator will give accurate elevation and azimuth angle. it is designed and simulated by using RT/DUROID 5880 substrate at the operating frequency 17GHz improve the performances. After a theoretical study on the use of open stubs, we present the simulation results of this mono pulse comparator by using CST Microwave Studio. Good agreement is found simulation. in this we follow to steps one is to design hybrid coupler and second one is adding extra 900 bend line to the hybrid coupler by integrating combination of this type four hybrid coupler we get four out put channels in that one sum port, two difference ports, one termination port.
