Embodiment Construction

[0019] Attached below Figure 1-4 The present invention is further described:

[0020] The invention relates to a dual-polarization antenna based on multilateral coupling. The antenna adopts coaxial feeding and indirect feeding of radiation unit multilateral coupling, thereby realizing the dual-polarization design of the antenna, and can be flexible according to actual needs. It is convenient to realize the circular polarization or multi-band of the antenna. In addition, the antenna adopts a single-layer printing plate structure, and the profile height of the antenna is low, and the coaxial feeding structure of the antenna reduces the influence of the coaxial cable on the antenna radiation.

[0021] A dual-polarized antenna based on multilateral coupling, the dual-polarized antenna includes a dielectric substrate 1, a central diamond-shaped radiation unit 2 arranged on the dielectric substrate 1, a folded fan-shaped parasitic radiation unit 3-1, and a fan-shaped parasitic rad...

Abstract

The invention belongs to the dual polarized antenna field, and specifically relates to a dual polarized antenna based on multi-coupling; a central rhombus radiation unit is directly connected with a coaxial feed line, thus realizing probe feed; four folded sector parasitic radiation units and the central rhombus radiation unit can realize multi-coupling so as to realize indirect feed of the antenna; according to client needs, the dimensions, shape, placement position and angle of the sector radiation unit can be changed, thus fast and easily realizing dual polarization, circular polarization and multiband of the dual polarized antenna. In addition, the antenna is low in profile, small in sizes, easy and flexible to design, and can be installed in a base station and terminal equipment.

Description

technical field [0001] The invention belongs to the field of dual-polarized antennas, and in particular relates to a dual-polarized antenna based on multilateral coupling. Background technique [0002] With the rapid development of the mobile communication business all over the world, it brings convenience and speed to our daily life. Now people's requirements for mobile communication are not limited to the transmission of voice signals, but the requirements for multimedia signals such as data, images, animations and videos are becoming more and more urgent, and the requirements for signal transmission quality are also getting higher and higher. With the development of microelectronics technology and the continuous improvement of cellular technology, the capacity and quality of mobile communication systems are constantly upgraded, which puts forward higher and higher performance index requirements for base station antennas. The base station antenna works in a complex mobile...
