Abstract

The invention discloses a corner reflector based wideband high-gain omnidirecitonal antenna. The corner reflector based wideband high-gain omnidirecitonal antenna comprises printing dipoles, a one-eight parallel feed network, a corner reflector, an array feed port, an upper connector, a lower connector, a one-four power division network, a base and a radio frequency connector, wherein the eight same printing dipoles are arranged at certain intervals into arrays which are printed on dielectric plates, and the dipole arrays are arranged on angular bisectors of the corner reflector. By grouping the printing dipoles, high-grain energy radiation of the antenna is achieved; with the adoption of the parallel feed network, the energy radiation direction stability of the antenna in a wide band is ensured, and the wideband working performance is achieved; and the dipole arrays are uniformly arranged at an interval of 90 degrees in a horizontal plane and are combined with the corner reflector, and thus, the omnidirecitonal radiation characteristic of high grain is achieved.

Description

technical field [0001] The invention relates to an omnidirectional radiation antenna, in particular to a broadband high-gain omnidirectional antenna. Background technique [0002] With the development of science and technology, the wireless communication business has been greatly popularized, and omnidirectional antennas are widely demanded in wireless communication. Generally, antennas with omnidirectional radiation characteristics are composed of dipole-type omnidirectional antenna elements, such as symmetrical dipoles, monopoles, biconical antennas, printed dipoles, etc., but the main disadvantage of this type of antenna is low gain. [0003] In order to realize the high gain of the omnidirectional antenna, the usual method is to form an array of omnidirectional antenna elements to form a linear array superimposed in the same direction. According to the way of feeding the array, the omnidirectional array can be divided into series feeding array and parallel feeding array...
