Radiation Characteristic Analysis of V/UHF Band Antennas Integrated on Aircraft using EM Tool

In this paper, V/UHF band blade monopole and circularly polarised UHF band cross dipole antennas are mounted on the aircraft. The radiation characteristic analysis of antennas placed on aircraft carried out using full wave and asymptotic hybrid solver. The two blade monopole antennas are placed on top & bottom and cross dipole antenna on top of the aircraft. The radiation patterns are getting distorted along length of aircraft, the nulls are observed in various cuts. The nulls are around 25dB, 20dB, and 22dB for top, bottom blade monopole antennas and a cross-dipole antenna placed on the aircraft respectively.
