Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0055] Please refer to figure 1 , is a schematic composition diagram of the first embodiment of the antenna of the present invention, and optionally, the antenna is an indoor ceiling antenna. Of course, in addition to the commonly used indoor ceiling installation scenario, the antenna in the embodiment of the present invention can also be used in other scenarios such as open outdoors, for example, the antenna can be supported by a high pole.

Abstract

The embodiment of the present invention discloses an antenna, including: two antenna arrays, each antenna array includes two microstrip antenna units; the feeding amplitudes of the two microstrip antenna units are equal, and the feeding phase difference is 180 degrees And the operating frequency is the same, the center distance between the two microstrip antenna units is between 0.5 wavelength and 1 wavelength of the center frequency of the working frequency band of any microstrip antenna unit; the angle between the two antenna arrays in the same plane Between 30 degrees and 150 degrees, and the midpoint of the center distance between the two microstrip antenna elements of the first antenna array in the two antenna arrays and the midpoint of the center distance between the two microstrip antenna elements of the second antenna array The distance between them is less than or equal to 3 wavelengths of the center frequency of the working frequency band of the microstrip antenna unit with the shortest wavelength. The embodiment of the invention also discloses a wireless signal transceiving system. By adopting the invention, the uniformity of the antenna radiation signal can be improved, and the blind area of ​​radiation coverage can be reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna and a wireless signal transceiving system. Background technique [0002] For indoor coverage scenarios of mobile communications, the most commonly used antenna installation method is ceiling installation, that is, installing the antenna on the ceiling. [0003] In the prior art, a dish cone antenna is usually used for ceiling installation. The end-fire array in the dish cone antenna is horizontally polarized. By cooperating with other vertically polarized antenna elements, it can meet the requirements of the ceiling antenna with low radiation in the normal direction and high radiation in the horizontal direction. refers to the radiation direction of the antenna, and the horizontal direction is perpendicular to the normal direction of the antenna. In order to expand the radiation range of the antenna in the horizontal direction, it is necessary to increase the t...
