Antenna structure suitable for 5G Internet of Things equipment and Internet of Things equipment

Abstract

The invention discloses an antenna structure suitable for 5G Internet of Things equipment and Internet of Things equipment. The antenna structure comprises a PCB, an antenna radiator, a grounding connecting piece and a feed connecting piece, and the antenna radiator is provided with a grounding point and a feed point; the antenna radiator is arranged above a PCB, the grounding point is connected with the PCB through the grounding connecting piece, and the feeding point is electrically connected with the PCB through the feeding connecting piece; the antenna radiator comprises a first radiation branch and a second radiation branch which are connected, the first radiation branch and the second radiation branch are located on the two sides of the grounding point and the feeding point respectively, and the first radiation branch and the second radiation branch are asymmetrically arranged; and the first radiation branch and the second radiation branch are different in length and width. According to the invention, good bandwidth coverage and good antenna performance can be obtained.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an antenna structure suitable for 5G Internet of Things equipment and the Internet of Things equipment. Background technique [0002] In recent years, with the rapid development of the Internet of Things, the communication technology of the Internet of Things has also been greatly improved. NB-IoT (Narrow Band Internet of Things, Narrowband Internet of Things) is one of the latest Internet of Things technologies. It is a new narrowband cellular communication LPWAN (Low- Power Wide-Area Network, Low Power Wide Area Network) technology. Compared with traditional 2G, 3G and 4G cellular communication technologies such as GSM, CDMA, WCDMA and LTE, NB-IoT can achieve massive access, ultra-low power consumption and cost, and at the same time, NB-IoT system can provide deep coverage , achieve strong penetration, and can co-site with the existing mobile communicat...

AI Technical Summary

Problems solved by technology

First, the introduction of components will increase the cost of the antenna system, the cost of production raw materials, and the cost of the process. Second, it is necessary to reserve corresponding space in the PCB circuit board to place additional radio frequency chips and peripheral circuits. This not only It increases the difficulty of the entire product circuit design, and also makes the already compact PCB design more difficult
