Terminal antenna signal tuning device and terminal

Abstract

The embodiment of the present invention discloses a terminal antenna signal tuning device and a terminal, which relate to the communication field and are used to provide an external or internal antenna device, which improves the radio frequency performance of the terminal and the performance compatibility of antennas in different forms. In the embodiment of the present invention, the body of the single-frequency whip antenna is connected to the circuit board of the terminal through the first feed point, and is used for tuning the transmitting body through the coupling branch when the body of the single-frequency whip antenna is in different states. and has a wireless signal at a target frequency point; the coupling branch is connected to the circuit board of the terminal through a second feed point, and is used to use the impedance value of the single-frequency rod antenna body in different states and the coupling The branch tunes the mutual impedance value generated by the single-frequency whip antenna body and the actual impedance value when the single-frequency whip antenna body is in different states; thereby solving the frequency offset problem of the single-frequency whip antenna in different states.

Description

technical field [0001] The present invention relates to the field of communications, and in particular to a terminal, a terminal antenna signal tuning device and the terminal. Background technique [0002] With the increasing development of wireless network technology, connecting to a local area network or the Internet through wireless (Wi-Fi, Wireless-Fidelity) has become a main networking way for various smart terminals. [0003] Traditional terminals use an external antenna to receive and transmit wireless signals, but the external antenna will hinder the user's operation when the user operates the horizontal screen. Therefore, the existing smart terminals mainly use the built-in antenna to receive or transmit wireless network signals. [0004] However, with the increasing functions of smart terminal equipment, the integration of various chips and modules inside the smart terminal equipment is getting higher and higher, resulting in fewer and fewer antenna clearance areas...

Problems solved by technology

[0004] However, with the increasing functions of smart terminal equipment, the integration of various chips and modules inside the smart terminal equipment is getting higher and higher, resulting in fewer and fewer antenna clearance areas for receiving and transmitting wireless signals. The nearby electromagnetic environment is becoming more and more complex, which leads to the degradation of the radio frequency performance of the antenna in the wireless module, resulting in the poor wireless signal of the smart terminal
