Antenna structure

Abstract

The invention provides an antenna structure. The antenna structure comprises a substrate, a radiation part, a grounding part, a first C-shaped groove and a second C-shaped groove, the substrate is rectangular; the radiation part is arranged on one surface of the substrate; the grounding part is arranged on the other surface of the substrate; the first C-shaped groove is formed in the grounding part and comprises a first groove part and two first groove pins; the two first groove pins convexly extend from the first groove part along the length direction of the substrate; the second C-shaped groove is formed in the grounding part, the second C-shaped groove and the first C-shaped groove are arranged at intervals in the length direction, the second C-shaped groove comprises a second groove part and two second groove feet, and the two second groove feet protrude from the second groove part in the length direction; and the first groove part is adjacent to the two second groove pins, the first C-shaped groove is operated in a first frequency band, and the second C-shaped groove is operated in a second frequency band. And the regulation and control capability of the antenna on dual frequency bands is improved through the double C-shaped grooves.

Description

technical field [0001] The present invention relates to an antenna structure, and in particular to an antenna structure applied to a dual-frequency system. Background technique [0002] Wireless network technology is becoming more and more mature. Through the antennas configured in various communication devices, the signals can be transmitted in the form of radio waves by changing the internal current and electric field, so that the transmission of information is no longer limited by physical transmission lines. With the deployment of a large number of base stations and artificial satellites, a cellular network is formed, and the various regions are further connected in series, and the signal transmission range can be spread all over the world, greatly improving the communication speed and convenience, such as the widely used in today's life Mobile phones are one application that has benefited from wireless networking technology. [0003] The frequency of radio waves is bet...

Problems solved by technology

[0004] There is a known Wi-Fi dual-band PCB antenna operating in the 2.4GHz to 2.5GHz and 5.15GHz to 5.85GHz frequency bands. The frequency modulation method is to adjust the gap (Slots) to make the impedance matching of the antenna reach the optimum value. However, When the external factors change, such as the material of the device casing, the relevant operators correspondingly change the length of the metal extension to adjust the antenna gain of one of the frequency bands, but instead make the other frequency band deviate from the original required range, causing the relevant operators to respond differently. All products must re-design the antenna and FM test
