Problems solved by technology

However, due to the inherent difference in H / V polarization characteristics, no matter what shape of the floor boundary is loaded, it is impossible to guarantee that the two patterns are completely consistent, especially the horizontal wave width HPBW and front-to-back ratio FTBR

Embodiment Construction

[0057] The preferred embodiments of the invention patent are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail. Here, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the preferred implementation examples described here are only used to illustrate and explain the present invention, and are not used to limit or limit the present invention.

[0058] Such as Figure 16 As shown, the wide-beam high-gain dual-polarization directional antenna includes reflectors, H / V crossed dipole arrays, and double-frame boundaries.

[0059] Such as Figure 13-Figure 18 As shown, the middle part of the reflector is a straight part 600, that is, the middle part of the reflector protrudes upwards to form a plane, and the two sides of the reflector are first bent downwards and then bent toward both sides to form bent parts, that is, the two sides of the...

Abstract

A wide-beam high-gain dual-polarization directional antenna comprises a reflecting plate, an H / V cross oscillator array and a dual-frame boundary. The middle part of the reflecting plate is a straightpart, and two sides are bending parts, wherein two pairs of L-shaped curled edges are symmetrically loaded on the edges of the two bent parts. An H / V cross oscillator array is arranged at the centerof the reflecting plate. Two sides of the H / V cross oscillator array are provided with double-frame boundaries partially arranged on the reflecting plate. The composite boundaries of the reflecting plate and the reflecting plate are reasonably designed, so as to match the H / V cross oscillator array. The directional base station antenna is wide in bandwidth, high in gain, ultra-wide in beam, dual in polarization, high in isolation, low in profile, low in cost and easy to produce.

Description

technical field [0001] The invention relates to mobile communication base station antenna equipment and technology, in particular to a wide-beam high-gain dual-polarization directional antenna. Background technique [0002] With the continuous increase of network deployment density, mobile communication has basically achieved wide-area continuous coverage of signals. However, limited by the operating frequency band and coverage area, it is difficult for macro cells to meet the requirements of high-speed data transmission and large system capacity. In contrast, the 5.8G ISM frequency band is license-free, has wide bandwidth, large capacity, good propagation characteristics, and small antenna size, which is very suitable for local high-speed data services with dense users. This type of base station or wireless access point (Access Point, AP) antenna usually covers the 5.15~5.85GHz frequency band (BW=12.73%), high gain (G>12dBi) and wide horizontal wave width (above 90°), d...
