Abstract
The present disclosure discloses a tunable antenna and a terminal. The tunable antenna 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.
