An omnidirectional antenna and electronic equipment

Abstract

The invention provides an omnidirectional antenna which comprises a dielectric substrate, a first radiation unit, a second radiation unit, a feeding unit and a grounding unit. The first radiation unit is arranged on a surface of the dielectric substrate and is in the shape of a combination of a trapezoid and a rectangle connecting with the bottom side of the trapezoid; the second radiation unit is in the shape of a combination of a trapezoid and a rectangle contacting with the bottom side of the trapezoid, and is opposite to the first radiation unit; the feeding unit is triangular, and one side of the feeding unit is connected with the first radiation unit; the grounding unit is triangular, one side of the grounding unit is connected with the second radiation unit, and the grounding unit is opposite to the feeding unit; and the first radiation unit and the second radiation unit respectively comprise a first radiation unit branch and a second radiation unit branch. The omnidirectional antenna is a dual-frequency broadband omnidirectional antenna and can work in two frequency bands, impedance of the omnidirectional antenna is adjustable, the bandwidth and the center frequency point of the omnidirectional antenna also can be adjusted as needed, electronic equipment comprising the omnidirectional antenna can transmit wireless signals on the basis of IEEE802.11, and the requirement on wireless signal coverage within a certain region can be met.

Description

technical field [0001] The invention relates to the field of wireless communication equipment, more specifically, to an omnidirectional antenna and electronic equipment using the omnidirectional antenna. Background technique [0002] In the wireless communication system, users have requirements for continuous improvement of data throughput, high QoS service quality and strong anti-interference ability of the wireless communication system. For example, in communication systems such as IEEE802.11a / g / h, a wireless access point (AP) transmits data with one or more wireless user equipments through a wireless link. The wireless UE may be susceptible to other access points, other wireless communication devices, changes or interference in the wireless link environment between the access point and the remote receiving point, and the like. The interference may greatly reduce the data transmission capability of the wireless link, or greatly increase the bit error rate and poor QoS ser...

AI Technical Summary

Problems solved by technology

The wireless user equipment may be susceptible to other access points, other wireless communication devices, changes or interference in the wireless link environment between the access point and the remote receiving point, etc.

This interference may greatly reduce the data transmission capacity of the wireless link, or greatly increase the bit error rate and poor QoS service quality, which may cause users to be unbearable
