Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0017] Such as Figure 1-Figure 4 As shown, what the present invention describes is a dual-broadband spotlight antenna. The dual-broadband spotlight antenna includes an integrated "L"-shaped reflector 1 composed of a horizontal plate 11 and a vertical plate 12. A vibrator fixing plate 2 parallel to the vertical plate 12 is installed in the middle of the horizontal plate 11 of the “L” type reflector 1, and a first broadband broadband parallel to the vertical plate 12 is installed on the upper part of one side of the vibrator fixing plate 2. The vibrator 3 and the second broadband vibrator 4 use the vibrator fixing plate 2 to fix the feeding coupling mode of the two vibrators, balance the current between the two vibrators, and change the dielectric constant between the vibrator and the coupling plate. The first broadband vibrator 3 and the second br...

Abstract

The invention relates to the technical field of antenna devices, and particularly discloses a double-broadband spotlight antenna. The double-broadband spotlight antenna comprises an L-type reflecting plate, wherein an oscillator fixing plate parallel to a vertical plate is mounted in the middle of a horizontal plate of the L-type reflecting plate; a first broadband type oscillator and a second broadband type oscillator, which are parallel to the vertical plate, are mounted at the upper part on one side of the oscillator fixing plate; the first broadband type oscillator is flush with the second broadband type oscillator; a gap is kept between the side parts of the first broadband type oscillator and the second broadband type oscillator; feeding points are respectively arranged on the first broadband type oscillator and the second broadband type oscillator; a rectangular coupling piece is mounted at one edge of the horizontal plate. According to the double-broadband spotlight antenna with a brand new structure, disclosed by the invention, the pair of broadband type oscillators, the L-type reflecting plate and the plurality of coupling pieces is used, and the shape of the broadband type oscillators is finely tuned, so that the antenna radiation performance can be improved; the double-broadband spotlight antenna is very suitable for being mounted in products such as the spotlight, and is small in size, simple in whole structure and convenient to assemble.

Description

Technical field: [0001] The invention relates to the technical field of antenna equipment, in particular to a double-broadband spotlight antenna. Background technique: [0002] Today, with the rapid development of wireless communication, the base station antenna, as the transceiver device of the communication system, has been continuously improved and improved. In order to send and receive multi-band signals at the same time, designers have developed various multi-band antennas, dual-broadband spotlight antennas, etc. At present, the dual-broadband spotlight antenna in the industry is mainly typical of the dual-broadband spotlight antenna, that is, the antenna is built into the spotlight for signal radiation. However, the existing spotlight antennas have problems such as high production cost, complex structure, large volume and difficult assembly, and it is difficult to further improve the radiation performance of the antenna. Invention content: [0003] The purpose of t...
