Novel ultra-wide frequency band radiating element and multi-band antenna comprising same

Abstract

The invention relates to the technical field of antenna equipment, in particular to a novel ultra-wide frequency band radiating element. The ultra-wide frequency band radiating element comprises a feed body, feed pieces and main radiation pieces, wherein the feed body comprises a base, four disconnected supporting bodies vertically extending upwards from the base and feed plates respectively formed on the outer sides of the upper end parts of the supporting bodies; each feed piece is connected between the upper end parts of each two opposite supporting bodies; the two feed pieces are arranged in a crossed manner and are not in contact with each other; one main radiation piece is arranged above each feed plate; the main radiation pieces are supported above the feed plates through insulation brackets. Compared with the existing ultra-wide frequency band radiating element, the radiating element, which adopts a brand new structure, covers low-frequency bands and is provided by the invention, has the advantages as follows: under the circumstance of the same performance, the size and height can be greatly reduced, the shielding effect on other frequency-band radiating elements on the two sides of the radiating element is greatly reduced, and meanwhile, mutual coupling among radiating element of different frequency bands is reduced.

Description

Technical field: [0001] The invention relates to the technical field of antenna equipment, in particular to a new type of ultra-wide frequency band radiation unit and a multi-frequency antenna containing the radiation unit. Background technique: [0002] In today's highly developed wireless communication, the base station antenna, as the transceiver device of the communication system, has been continuously improved and improved. In order to send and receive multi-band signals at the same time, designers have developed multi-frequency antennas. At present, the typical technology of multi-frequency antennas in the industry is the deformation of binary array antenna radiating elements or conventional symmetrical oscillators, which are all high in size, especially low-frequency radiation. The unit, due to its higher height, and the lower height of the high-frequency radiation unit, results in serious coupling and mutual shielding between different frequency bands, resulting in variou...

AI Technical Summary

Problems solved by technology

In order to send and receive multi-band signals at the same time, the designer has developed a multi-frequency antenna. At present, the typical technology of multi-frequency antennas in the industry is the deformation of the radiation unit of the binary array antenna or the form of a conventional symmetrical vibrator, and the size is relatively high, especially for low-frequency radiation. Due to its high height, the height of the high-frequency radiation unit is relatively low, resulting in serious coupling and mutual shielding between different frequency bands, resulting in various defects in the comprehensive index of the antenna
