Abstract

The invention discloses a wide-beam and high-gain antenna, comprising a cross oscillator pair arranged on a reflector and formed by a plurality of arrays, wherein the cross oscillator pair comprises pendulous wideband oscillators printed on two dielectric substrates respectively; the two pendulous wideband oscillators are cross, two arms of the oscillator are symmetric inverse L-shaped sheets with each including a vertical section and a horizontal extended section at the top of the vertical section, and the tail end of the horizontal extended section is a downward bent section; a parasitic unit is arranged on the upper side of the oscillator arm, a microstrip line is arranged on the other side of each of the two dielectric substrates, and the reflector is used for dual-polarized feed. The parasitic units are arranged on the upper side of the oscillator arms, thus realizing wide beams and good matching of single PCB (Printed Circuit Board) cross oscillators; and the wide-beam wideband PCB cross oscillator arrays obtain the characteristics of dual polarization, horizontal wide beams and high-gain radiation. The method is simple to implement, low in cost and suitable for batch production, and is applicable and effective for design and improvement of conventional wideband and high-gain oscillator antennas.

Description

【Technical field】 [0001] The invention relates to a mobile communication base station antenna device and technology, in particular to a wide-beam high-gain antenna and its technology. 【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 data transmission rate and large system capacity. In contrast, the 5.8G frequency band 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 antenna needs to have the characteristics of large bandwidth (4.97-5.85GHz, BW=16.27%), high gain and wide (horizontal) wave width, so as to cover a large area and serve more users, so as to obtain good coverag...
