摘要：
The transmission mode of coaxial waveguide is TEM mode, based on the transmission characteristic, a dual-polarization waveguide antenna with high radiation efficiency and good cross polarization characteristics is presented. The waveguide antenna adopts the structure form of rectangular coaxial waveguide, its cutoff frequency is equal to zeros, by means of taking advantage of the transmission characteristic of the coaxial waveguide, this article reduces the cross section size and achieves the miniaturization,lightweight design. Compared with conventional waveguide antenna, the results show that the rectangular coaxial dual-polarization waveguide antenna has the characteristics of high polarization purity and high radiation efficiency; at the same time, its weight is reduced by more than 30% and its profile is reduced by more than 40%, providing new ideas for the miniaturization and lightweight design of waveguide antennas, possessing certain engineering application value.
