ADJUSTABLE ANTENNA AND TERMINAL

摘要

The present invention relates to the technical field of communications, and disclosed are an adjustable antenna and a terminal which solve the technical problem of an adjusted frequency band range being narrow when an adjustable antenna is tuned in the prior art. The adjustable antenna comprises: a circuit board; an antenna body for transceiving a signal of a first frequency band and comprising a feeding end and a grounding pin, the feeding end being provided on the circuit board; and an electrical tuning network, a grounding point provided on the circuit board being connected to a grounding pin of the antenna body through the electrical tuning network. The electrical tuning network comprises: a first adjustable capacitor with adjustable inductance and capacitance values, wherein a loading value of the inductance is changed by adjusting a first capacitance value of the first adjustable capacitor, thus changing the first valid electrical length of the antenna body.
