Abstract

The invention discloses a novel 5G millimeter wave dual-polarization horn antenna, and relates to the technical field of horn antennas. The antenna includes an upper plate, a lower plate, a front plate, a rear plate and a cover plate, the cover plate is located at the rear end of the antenna, the front plate and the rear plate are located between the upper plate and the lower plate, the upper plate The inside of the plate, lower plate, front plate, rear plate and cover plate forms an excitation cavity structure, and the cavity structure is formed with an excitation cavity whose cross section is rectangular and the cross section gradually decreases from right to left and then remains constant. cavity, the left end of the excitation cavity is closed by the cover plate, a curved ridge is formed on the upper plate, lower plate, front plate and rear plate in the excitation cavity, and the angle between the ridges is 90° °, several Archimedes spiral curves are formed on the curved ridge. The antenna can improve the symmetry of the E-plane and H-plane pattern, the high-frequency pattern is more stable, and the gain flatness is improved.

Description

technical field [0001] The invention relates to the technical field of horn antennas, in particular to a novel dual-polarized horn antenna for 5G millimeter waves. Background technique [0002] At present, a large number of 5G consumer electronic products are in the research and development verification stage, and their performance needs to be verified urgently. At present, test antennas in the millimeter wave band (test frequency ranges from 18GHz to 50GHz) are monopolized by foreign suppliers. As a result, the price of the antenna is high and the delivery period is long, which cannot cope with the explosive growth of domestic demand. Due to the characteristics of 5G, a 360° spherical scan is required for each product during the test to confirm the quality of its antenna. The traditional test method is to use multiple single-polarized antennas to form a test antenna array to scan the product in all directions (multiple antennas are tested instead of rotating). The symmet...
