[0028] FIG. 2(a), FIG. 2(b) and FIG. 2(c) are respectively a perspective view, a front view and a top view of a broadband dual-polarized omnidirectional antenna provided by Embodiment 1 of the present invention.

[0029] A broadband dual-polarized omnidirectional antenna in Embodiment 1 of the present invention includes a bottom plate 10 , a vertically polarized antenna 20 , a horizontally polarized antenna 30 and a support column 40 . The vertically polarized antenna 20 is vertically placed on the base plate 10, the vertically polarized antenna 20 and the horizontally polarized antenna 30 are coaxially arranged, and the support column 40 is fixed on the base plate 10 and the horizontally polarized antenna 30 for supporting the horizontally polarized antenna 30.

[0030] In addition to supporting the attachment plate 32 , the supporting column 40 can also be used to adjust the standing wave by adjusting the height of the supporting column 40 to widen the frequency bandwidth of...

Embodiment 2

[0047] Embodiment 2 of the present invention provides a broadband dual-polarized omnidirectional antenna and feeding method provided in Embodiment 1 of the present invention. When using the antenna to receive radio waves, use the horizontally polarized antenna to receive horizontally polarized waves , using a vertically polarized antenna to receive vertically polarized waves, and convert the received radio waves into high-frequency currents and output them through the first feeder and the second feeder; when using the antenna to transmit radio waves, the received high-frequency After the current is converted into radio waves, it is output to the antenna through the first feeder and the second feeder. The antenna uses a horizontally polarized antenna to emit horizontally polarized waves, and uses a vertically polarized antenna to emit vertically polarized waves.

[0048] The broadband dual-polarized omnidirectional antenna provided in the embodiment of the present invention not ...

Abstract

The invention provides a broadband double polarization omnidirectional antenna and a feed method. The feed method concretely comprises the following steps that with the adoption of coaxial arrangement of a horizontal polarization antenna and a vertical polarization antenna, the horizontal polarization antenna are respectively adhered to the upper surface and the lower surface of an adhesion platethrough two vibration arms of a folded dipole; in addition, the two vibration arms are respectively connected with the structures of a feeder inner conductor and a feeder outer conductor, so that thedouble polarization antenna has wider working frequency band width; and meanwhile, the double polarization ceiling antenna has good polarization isolation effect and covering balance, can effectivelyexert the performance of an MIMO antenna in LTE and WLAN systems and can be effectively applied to a 2G network and a 3G network so that the data transmission rate is increased.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a broadband dual-polarized omnidirectional antenna and a feeding method. Background technique [0002] In the Advanced International Mobile Telecommunications (IMT-Advanced) system, the two technology camps of Time Division Duplexing (TDD) and Frequency Division Duplexing (FDD) both use multiple input and multiple output (multi-input- multi-output, MIMO) antenna technology. [0003] MIMO antenna technology refers to the use of multiple transmitting antennas and multiple receiving antennas at the transmitting end and receiving end respectively, and radio wave signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving the service quality of each user (bit error rate or data rate). Compared with the traditional single-input-single-output (SISO) antenna system, the MIMO antenna system can improve spectrum utilizati...
