Matching Design of Wedge-Shaped Structure Radome and Dual linear Polarized SNA

This paper first introduces a design scheme of dual polarized Vivaldi antenna with cross array, which is suitable for internal in wedged-shaped structure radome. The cross-array scheme can improve the influence of radome on the electrical performance of dual linear polarized antenna and have low cross-polarization in E-plane and H-plane, but have high cross-polarization in the non-principal planes. The Sliced Notch Antenna (SNA) have good cross-polarization radio (CPR) in all planes, this paper gives the simulation results and shed light on the method for matching design of Wedge-Shaped Structure radome and Dual linear Polarized SNA.
