Abstract

The invention discloses a high-efficiency low-profile dual-linear polarization horn array antenna, and belongs to the technical field of antenna feed sources. The antenna sequentially comprises a cross-shaped grid layer, a waveguide horn layer, a feed network layer and a back cavity layer from top to bottom. A cross intersection point in the cross grid layer is located in the center of the waveguide horn mouth, the waveguide horn mouth adopts a multi-stage step transition structure, the feed network layer comprises a horizontal polarization feed network and a vertical polarization feed network, the horizontal polarization feed network and the vertical polarization feed network both adopt quasi-air strip line structures, and the array feed port adopts a waveguide-to-strip line feed form. According to the invention, through reasonable layout, two sets of feed networks are designed in a limited space, adjacent units feed in a reverse direction, and meanwhile, the horn adopts a multi-stage step structure and is combined with a waveguide-to-strip line feed structure, so that the high-efficiency low-profile dual-linear polarization characteristic of the array is realized.

Description

technical field [0001] The invention relates to the technical field of antenna feeds, in particular to a high-efficiency and low-profile dual-line polarized horn array antenna. Background technique [0002] With the development of mobile communications, especially satellite communications, dual-linear polarized antenna systems and dual-circularly polarized antenna systems derived from dual linear polarization have received more and more attention. At the same time, the terminal's requirements for low profile and high efficiency of the antenna are also getting higher and higher. The traditional reflector antenna has a high profile, while the microstrip array antenna can achieve a low profile, but due to the strict requirements of dielectric loss and process, its Efficiency is difficult to reach a high level. [0003] As a classic antenna form, the horn antenna has the characteristics of high efficiency, stable structure, high reliability and mature technology. The horn anten...
