Abstract

The invention discloses an ultra wide band horizontal polarized horizontal omnidirectional antenna, comprising at least three arms integrated antenna elements. The arms integrated antenna elements comprises a folded dipole element and a parallel feeder. The folded dipole element comprises two inverted U shaped conductor sheets that are mirror symmetric as the upper arm and the lower arm. The right ends of the two inverted U shaped conductor sheets are connected by bent portion. The left ends of the two inverted U shaped conductor sheets are disconnected and respectively connected with one of two parallel feeders. The at least three arms integrated antenna elements are rotationally distributed around a center point. The parallel feeder converges at the center point. The center point is a feed point. The ultra wide band horizontal polarized horizontal omnidirectional antenna utilizes a folded dipole as a radiation element, in order to obtain the high impedance and fed and broadband after arraying and parallel feed. The ultra wide band horizontal polarized horizontal omnidirectional antenna increases gains significantly, optimizes the maximum radiation direction, puts up and down into the ideal level, obtains better cross polarization ratio and improves efficiency significantly. The ultra wide bandwidth simplifies the design of feed network, and is more convenient to debug and optimize.

Description

[0001] 【Technical field】 [0002] The invention relates to a wireless communication antenna device and technology, in particular to an ultra-wideband horizontally polarized horizontal omnidirectional antenna and its technology. [0003] 【Background technique】 [0004] Omnidirectional antenna is an important antenna type in the field of wireless communication. Theoretically, the calculation of antenna gain requires an ideal omnidirectional antenna with uniform radiation in all directions as a reference. In engineering, omnidirectional antennas with uniform radiation only in a certain plane, such as the horizontal plane, are widely used in typical scenarios such as vehicle antennas, wireless routers and other terminal equipment. Since the position and orientation of the terminal equipment relative to the base station transmitter is arbitrary, the use of an omnidirectional antenna can not only ensure a good communication effect, but also reduce the size and cost of the equipment....
