Abstract

The thin substrate vibrator difference beam planar horn antenna relates to a horn antenna. The antenna includes a microstrip feeder (2), a horn antenna (3) and a vibrator (4) on a dielectric substrate (1), and the horn antenna (3) consists of a first metal plane (7), a second metal plane (8) Composed of two rows of metallized via hole horn side walls (9), the horn antenna (3) has an odd number of metallized via hole arrays (11) and an even number of dielectric filled waveguides (17), on the horn antenna (3) aperture surface Each dielectric-filled waveguide (17) on (10) is connected with a vibrator (4), and the left half antenna (15) and the connected vibrator (4) are symmetrical to the right half antenna (16) and the connected vibrator (4). The polarization direction of the radiation field of the antenna is parallel to the substrate, and the antenna can be manufactured using a thin substrate with high gain, large zero depth, low cost and compact structure.

Description

Technical field [0001] The present invention involves a speaker antenna, especially a thin -foundation tabs differential wave beam flat horn. Background technique [0002] The speaker antenna has a wide range of applications in satellite communications, ground microwave links, and radio telescopes.However, the huge geometric size of the three -dimensional speaker antenna restricts its application and development in the plane circuit.In recent years, the proposal and development of substrate integrated waveguide technology has promoted the development of the plane speaker antenna.The substrate integrated waveguide has the advantages of small size, light weight, easy integration and processing.In addition to the characteristics of the flat -based integrated waveguide plane horn, in addition to the characteristics of the speaker antenna, it also achieves the miniaturization and lightness of the speaker antenna, and it is easy to integrate in the microwave millimeter wave plane circu...
