Abstract
A matching circuit for an antenna of whatever type, includes a ground circuit and a feed circuit. The ground circuit connects a ground terminal of the antenna to a ground voltage, and provides an inductive impedance between the ground terminal and the ground voltage. The feed circuit connects a feed signal to a feed terminal of the antenna. The feed circuit is capable of switching between a first mode and a second mode for respectively providing a first equivalent impedance and a second equivalent impedance between the feed signal and the feed terminal. An associated method is also disclosed.
