Generation of Patterns of E-Plane Horn Antenna Using Tapered Amplitude Distribution
Abstract: In this paper, analysis is made to generating directional patterns on E-plane sectoral horn antenna for radar applications. In literature survey, the work on E-plane sectoral horn antenna is inadequate. For radar applications need low EMI (Electro Magnetic Interference) to enhance this we attempted work on horn antennas and achieved low interference. To the implementation of horn antenna we used tapered amplitude distribution method to reduce the EMI.
