Omnidirectional antenna and electronic device

Abstract

The invention provides an omnidirectional antenna and an electronic device. The antenna comprises a dielectric substrate including two surfaces, a first radiation unit and a second radiation unit, wherein the first radiation unit is arranged on one surface of the dielectric substrate and comprises a first long arm and a first short arm a certain distance away from the first long arm; and the second radiation unit comprises a second long arm and a second short arm a certain distance away from the second long arm, the second long arm and the second short arm are respectively opposite to the first short arm and the first long arm, and a gap is formed between the first long arm and the second long arm. The omnidirectional antenna provided by the invention is a dual-frequency broadband omnidirectional antenna, can work in two frequency bands; the impedance is adjustable and the center frequency point can also be adjusted as required; and an electronic device employing the omnidirectional antenna can achieve wireless signal transmission based on IEEE 802.11, and can meet the demand of wireless signal coverage within a certain region.

Description

technical field [0001] The invention relates to the field of wireless communication equipment, more specifically, to an omnidirectional antenna and an electronic device 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 to and from one or more wireless user equipment 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 Q...

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
