Body of Revolution Conical Vivaldi Antenna for Phased Array Applications

A Conical Body of Revolution (BOR) 5x5 element planar antenna array for electronic warfare phased array applications in the frequency range of 5-19 GHz is designed, analysed and Simulated. The proposed antenna array can scan up to±45o from broadside. The return loss, gain and radiation patterns in E-H planes are measured through simulation (Ansys HFSS-15.0 software). It is checked that the antenna provides moderate gain of 6 dB at 18 GHz frequency and radiation patterns are unidirectional and satisfactory. The primary advantage of the proposed antenna is its miniaturized size and simple structure.
