Abstract: In this paper we are planning to realize radiation pattern of a Unidirectional Yagi-Uda antenna using USRP2 which is connected with GNU Radio. Our basic approach is to get radiation pattern for H-plane structured Yagi-Uda antenna at different angles (0-360?). The proposed method is of low cost and easy to implement with two USRP, two PC and a Yagi-Uda antenna. The platform which we have used for getting radiation pattern values is GNU Radio which is open source software.Yagi-Uda antenna is used for long distance communication since it has good directivity. It is designed with three pairs of oscillator, directors and active transducer. Oscillator is connected to the voltage feeder and active transducer incapacitates the wave from different sides of antenna
