Novel head-to-end connected broadband omnidirectional antenna

Abstract

The invention discloses a novel head-to-end connected broadband omnidirectional antenna, comprising a hexagonal wideband vibrator, a printed board, feeder pillars and a reflecting plate. The hexagonalwideband vibrator is a copper cladding layer on the printed board. The inner and outer conductors of the feeder pillar are respectively communicated with the hexagonal wideband vibrator, and the bottom of the feeder pillar is fixed on the reflecting plate. The hexagonal wideband vibrator forms a circle by surrounding six hexagonal copper clad sheets in a consistent shape around the center in an axial symmetry manner. Two edges of the each hexagonal copper clad sheet are respectively connected with inner and outer conductors of adjacent feeder pillars. The shapes of the six hexagonal copper clad sheets in the consistent shape are symmetric on both sides, and the hexagonal copper clad sheet is a combination of two triangles and one rectangle. Beneficial effects are that the antenna has working characteristics of a broadband horizontal polarized omnidirectional antenna, can be widely used in design of broadband horizontal polarized omnidirectional antenna in various frequency bands. Theantenna has very good practical prospect in the fields of broadband communication and electronic analog and interference.

Description

Technical field [0001] The invention relates to an antenna, in particular to a new end-to-end connection type broadband omnidirectional antenna. Background technique [0002] In the communications field, with the rapid increase in data traffic demand and the design requirements of multiple systems sharing antennas, the wideband requirements for passive antennas are getting higher and higher; in the field of electronic countermeasures or interference, broadband antennas have always been the most important requirement. One of the prerequisites for preparation. Applied in specific scenarios, in order to achieve 360-degree coverage without blind spots, omnidirectional antennas have their own unique uses. [0003] Among the existing broadband omnidirectional antennas, (a dual-polarized ceiling antenna, utility model patent, Gaofeng, etc., application number 201020264189.2), the working frequency band of the patented horizontally polarized antenna is 1700MHz~2500MHz, and the relative ba...

Problems solved by technology

[0003] Among the existing broadband omnidirectional antennas, (a dual-polarized ceiling antenna, utility model patent, Gao Feng, etc., application number 201020264189.2), the working frequency band of the patented horizontally polarized antenna is 1700MHz~2500MHz, and the relative bandwidth reaches 40 %, it has certain broadband conditions, but the frequency band coverage has not reached frequency doubling, and the use environment has great limitations; another omnidirectional ceiling antenna, (a broadband dual-polarized omnidirectional antenna and feed method, invention patent, Gao Feng, Ma Xinghua, etc., application number 201010504764.6), the same horizontally polarized omnidirectional antenna has relatively narrow bandwidth, and different directions in the frequency band Figure 1 There is a big difference in consistency, and the antenna feed system is relatively complicated

[0004] To sum up, the existing horizontally polarized omnidirectional antennas generally face defects such as the working bandwidth cannot reach frequency doubling, the gain fluctuation in the frequency band is large, and the structure is relatively complicated.
