Abstract

The invention relates to a horn antenna, in particular to a thin-substrate vibrator difference beam plane horn antenna which comprises a micro-strip feeder line (2), a horn antenna body (3) and vibrators (4), and the micro-strip feeder line (2), the horn antenna body (3) and the vibrators (4) are arranged on a dielectric substrate (1). The horn antenna body (3) is composed of a first metal plane (7), a second metal plane (8) and two rows of metalized via hole horn side walls (9), odd-number metalized via hole arrays (11) and even-number dielectric-loaded waveguides (17) are arranged in the horn antenna body (3), the dielectric-loaded waveguides (17) are connected with the vibrators (4) respectively on the caliber face (10) of the horn antenna body (3), and the vibrators (4) connected with the left half antenna (15) is symmetrical with the vibrators (4) connected with the right half antenna (16). The polarization direction of an antenna radiation field is parallel with the substrate. The antenna can be made through a thin substrate, and is high in gain, large in zero depth, low in cost and compact in structure.

Description

technical field [0001] The invention relates to a horn antenna, in particular to a planar horn antenna with a thin-substrate dipole differential beam. Background technique [0002] Horn antennas are widely used in systems such as satellite communications, ground microwave links, and radio telescopes. However, the huge geometric size of the three-dimensional horn antenna restricts its application and development in planar circuits. In recent years, the proposal and development of substrate-integrated waveguide technology have greatly promoted the development of planar horn antennas. The substrate-integrated waveguide has the advantages of small size, light weight, easy integration and fabrication. The planar substrate-integrated waveguide horn antenna based on the planar substrate-integrated waveguide not only has the characteristics of the horn antenna, but also realizes the miniaturization and light weight of the horn antenna, and is easy to integrate in the microwave a...
