An antenna receiving device

Abstract

The invention relates to an antenna receiving device. An antenna is formed by superposing two metal wires with the same shape. Each metal wire is bent to a three-ring structure, specifically, an opened-type large ring and two opened-type small rings, wherein the opened-type large ring is provided with three openings, and the two opened-type small rings have the same shape and are respectively provided with one opening. For each metal wire, two ends of the openings of the two opened-type small rings are respectively connected to the corresponding top opening of the opened-type large ring in series; when the opened-type large ring is vertically placed, the bottom of the opened-type large ring is symmetrical horizontally-placed portions, the bottom opening of the opened-type large ring is correspondingly formed in the middle of the symmetrical horizontally-placed portions, the two ends of the bottom opening of the opened-type large ring and the horizontally-placed portions connected with the two ends respectively form a 90-degree included angle, the opened-type large ring is placed on a circuit board in a flat mode and welded with the circuit board, and the circuit board is parallel with the same horizontal plane of the opened-type large ring and the two opened-type small rings. The size of the antenna can be reduced by 20%, the width of the antenna can be reduced by 80%, and therefore the antenna receiving device is more suitable for being used indoors; meanwhile, antenna gain is improved by 20% compared with existing antenna gain, and the antenna receiving device can also receive signals clearly when used outdoors.

Description

technical field [0001] The present invention relates to the technical field of wireless communication equipment, in particular to an antenna receiving device. Background technique [0002] Antenna is one of the important components in the field of wireless communication. With the development of wireless communication technology, there are more and more types of antennas, and the scope of the antennas is getting wider and wider. Although there are many types of existing antennas , but the overall quality varies, for example, see attached Figure 5 As shown, it is a common outdoor antenna, which contains four loop antennas 21, three double parallel wires 22, a circuit board 23, and a coaxial cable 24, and the four loop antennas 21 are on the same plane and arranged in a straight line. Two adjacent loop antennas 21 are connected with a pair of parallel wires 22, wherein the two ends of the second pair of parallel wires 22 are respectively connected to the circuit board 23, and ...

[0002] Antenna is one of the important components in the field of wireless communication. With the development of wireless communication technology, there are more and more types of antennas, and the scope of the antennas is getting wider and wider. Although there are many types of existing antennas , but the overall quality varies, for example, see attached Figure 5 As shown, it is a common outdoor antenna, which contains four loop antennas 21, three double parallel wires 22, a circuit board 23, and a coaxial cable 24, and the four loop antennas 21 are on the same plane and arranged in a straight line. Two adjacent loop antennas 21 are connected with a pair of parallel wires 22, wherein the two ends of the second pair of parallel wires 22 are respectively connected to the circuit board 23, and the signal end and the signal output end of the circuit board 23 are respectively connected to the circuit board 23. The ground end of the coaxial cable 24 is connected to the signal end. Although the receiving signal effect of this type of antenna is good, the volume of this type of antenna is not suitable for indoor use; refer to the attached Image 6 As shown, it is an indoor antenna structure, which mainly includes a loop antenna 31, a substrate 32 and a coaxial cable 33, wherein the two ends of the loop antenna 31 are respectively inserted into the substrate 32, and are connected to the ground terminal of the coaxial cable 33 and the signal Although the size of this antenna is smaller than the above-mentioned outdoor antenna, it is easy to be placed indoors, but the volume of the loop antenna 31 of this antenna is still relatively large, and the receiving effect of this antenna is worse than that of the above-mentioned outdoor antenna. At the same time, because the loop antenna 31 is connected to the substrate 32 at a vertical angle, the overall volume cannot be reduced any further, so there is still a need for further improvement for the current indoor antenna device design.
