Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Existing planar antennas all have the structure of an antenna base plate plus two sides, and for high-frequency planar antennas, especially 1710MHZ-2500MHZ planar antennas, the length of the antenna base plate 1 is 1200 mm to 2800 mm, and the width is 140 mm- 160 mm, the height of the sides is fixed at 25 mm, and the thickness of the aluminum plate is 2 mm. The front-to-rear ratio of this conventional high-frequency panel antenna is generally between 16-18db.

[0016] Such as figure 1 , figure 2 As shown, in the high-frequency panel antenna provided by the present invention, each side of the antenna base plate has two sides, the outer side 3 and the inner side 4, and the heights of the two sides are not equal, and the outer side 3 is larger than the inner side Side 4 is high. Such a structure has been tested, and the front-to-back ratio is over 23db.

Abstract

The invention provides a double-side-edge high-frequency planar antenna, and relates to an antenna, in particular to a high-frequency planar antenna with the 2500 MHZ-2700 MHZ frequency band. An existing high-frequency planar antenna can not meet existing requirements because the front-to-back ratio of the existing high-frequency planar antenna is lower than the national standard. The high-frequency planar antenna comprises an antenna bottom plate (1) and side edges (2), wherein the side edges (2) are located on the two sides of the antenna bottom plate (1) and fixedly connected with the antenna bottom plate (1). The high-frequency planar antenna is characterized in that each side of the antenna bottom plate (1) is provided with two side edges (2), wherein the two side edges (2) on each side of the antenna bottom plate (1) are different in height, and the outer side edge (3) is higher than the inner side edge (4). The front-to-back ratio of the high-frequency planar antenna is higher than the national standard. In addition, the high-frequency planar antenna is simple in structure, can be obtained just by simply improving an existing structure, but is good in effect.

Description

technical field [0001] The invention relates to an antenna, in particular to a high-frequency panel antenna in the 2500MHZ-2700MHZ frequency band. Background technique [0002] For high-frequency panel antennas, the national standard for base station antennas has a front-to-back ratio of 16db or higher, and high frequencies are in the 2500MHZ-2700MHZ frequency band. With the development of 4G, high-frequency applications are widely used. In many cases, the front-to-back ratio needs to be greater than or equal to 16db. It is equal to 20db. 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 high-frequency flat-panel antenna cannot meet the existing needs because the front and rear are lower than the national standard. [0005] 2. Technical solution: [0006] In order to solve the above problems, the present invention provides a double-sided high-frequ...
