Problems solved by technology

[0003] In the limited space environment of the terminal equipment, if more antennas are arranged, the aperture of the antenna may be reduced, so that the bandwidth covered by the antenna is reduced, and the distance between the multiple antennas arranged in the small space is small, It may cause the same-frequency isolation problem of the antenna, which seriously affects the communication quality

Embodiment Construction

[0049] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0050] For the convenience of understanding, the technical terms involved in this application are explained and described below.

[0051] Wireless fidelity (wireless fidelity, WIFI) is a wireless network transmission technology that converts wired network signals into wireless signals for reception by related terminal equipment that supports its technology. WIFI can also be expressed as "Wi-Fi", "WiFi", "Wifi" or "wifi". A terminal device capable of supporting wifi connection needs to be equipped with a wifi antenna for sending and receiving signals. The working frequency band of the wifi antenna includes 2.4GHz to 2.5GHz. The wifi operating on the 5GHz frequency band is called wifi 5G, sometimes also called 5G wifi, which uses the 802.11ac protocol standard.

[0052] N77, N78 and N79 are the 5G new radio (NR) frequency bands cu...

Abstract

The present application provides a terminal antenna structure and a terminal, including: a first radiator, where the first radiator is used to transmit signals in a first frequency band, wherein at least part of the frequency bands in the first frequency band are higher than a preset frequency; Two radiators, the second radiator is used to transmit signals of the second frequency band, and the second frequency band overlaps with the first frequency band; a parasitic branch, the parasitic branch is arranged on the first radiator and the second radiator Between, used to reduce the current coupling of the second radiator due to the operation of the first radiator in the overlapping frequency band, the fundamental mode frequency of the parasitic branch is not higher than the preset frequency and / or the N of the parasitic branch The multiplier is higher than the preset frequency, where N is greater than or equal to 2. The isolation of the first radiator and the second radiator in the overlapping frequency band can be improved by setting the parasitic stubs, and the bandwidth of the first radiator can be broadened by using the fundamental mode resonance and N-fold frequency resonance of the parasitic stubs, thereby improving communication quality.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, relate to a terminal antenna structure and a terminal. Background technique [0002] With the development of mobile communication technology, the frequency spectrum resources used by wireless communication are increasing day by day, and the number of antennas used by terminal equipment also needs to increase synchronously. [0003] In the limited space environment of the terminal equipment, if more antennas are arranged, the aperture of the antenna may be reduced, so that the bandwidth covered by the antenna is reduced, and the distance between the multiple antennas arranged in the small space is small, It may cause the same-frequency isolation problem of the antenna, which seriously affects the communication quality. Contents of the invention [0004] Embodiments of the present application provide a terminal antenna structure and a terminal, which c...
