Title:
Adjustable antenna and terminal
Document Type and Number:
Japanese Patent JP6290410
Kind Code:
B2
Abstract:
The present invention relates to the field of communications technologies and discloses a tunable antenna and a terminal, so as to resolve a technical problem in the prior art that a tunable frequency band range is relatively narrow when a tunable antenna is tuned. The tunable antenna specifically includes: a circuit board; an antenna body, configured to transmit and receive a signal of a first frequency band and including a feed end and a ground pin, where the feed end is disposed on the circuit board; and an electrical tuning network, where a ground point disposed on the circuit board is connected to the ground pin of the antenna body by using the electrical tuning network, and the electrical tuning network includes an inductor and a first tunable capacitor with a tunable capacitance value, where a load value of the inductor is changed by tuning a first capacitance value of the first tunable capacitor, so that a first effective electrical length of the antenna body is changed.
