Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Existing flat antennas all have the structure of antenna bottom plate plus two sides, and for low-frequency flat antennas, especially 824MHZ-960MHZ flat antennas, the length of the antenna bottom plate 1 is 1200 mm to 2800 mm, and the width is 300 mm to 350 mm. mm, the height of the side is fixed at 50 mm, and the thickness of the aluminum plate is 2 mm.

[0021] The conventional shape of the panel antenna is that there is a side 2 on both sides of the antenna base plate 1 . Under this structure, the front-to-back ratio of the low-frequency panel antenna can meet the national standard, but only meet the national standard.

[0022] Compared with the existing low-frequency panel antenna, the low-frequency panel antenna of the present invention has two aspects of improvement, 1. There are two sides on each side of the antenna base plate, two para...

Abstract

The invention relates to antennas, in particular to a 824MHZ-960MHZ low-frequency planar antenna. The existing low-frequency planar antenna is incapable of meeting existing demands because the national front-to-rear ratio standard is low. The low-frequency planar antenna with a high front-to-rear ratio comprises an antenna bottom plate (1) and side edges (2), the side edges (2) are located at two sides of the antenna bottom plate (1) and firmly connected with the antenna bottom plate (1), there are two side edges (2) at each side of the antenna bottom plate (1), at two sides of the antenna bottom plate (1), and the end of at least one side edge of each side not in contact with the antenna bottom plate (1) is wave-shaped. The low-frequency planar antenna is simple in structure and easy to process, the front-to-rear ratio arrives at 30 db under the best state, and the front-to-rear ratio is greatly higher than the national standard and basically meets the existing demands.

Description

technical field [0001] The invention relates to an antenna, in particular to a low-frequency panel antenna in the 824MHZ-960MHZ frequency band. Background technique [0002] For low-frequency panel antennas, the front-to-back ratio of the base station antenna national standard is greater than or equal to 16db. Greater than or equal to 20db, and even greater than or equal to 25db. Generally, the structure of a panel antenna is a base plate plus two sides. Contents of the invention [0003] 1. Technical problems to be solved: [0004] The existing low-frequency flat-panel antenna cannot meet the existing needs because the front and rear are lower than the national standard. 2. Technical solution: [0005] In order to solve the above problems, the present invention provides a low-frequency panel antenna with a high front-to-back ratio, including an antenna base plate 1 and side edges 2, the side edges 2 are located on both sides of the antenna base plate 1, and are fi...
