Design and Implementation of a New Missile-borne Conical Conformal Antenna

摘要

In this paper, a conical missile-borne conformal antenna is proposed to meet a specific application. To achieve good omnidirectional circularly polarized (CP) radiation, the proposed antenna array is consisted of four identical CP microstrip antennas, which are distributed around the projectile. Shifter network and optimized patch is used to get CP performance for each antenna. The measured results are in good agreement with the simulation one. The experimental results show that the axial ratio (AR) of element antenna is less than 3 dB and omni-axis ratio is less than 6dB. The pattern of antenna in the horizontal direction is circular, with un-roundness less than 2 dB and the vertical pattern is "8".
