摘要：
An antenna tuner provides a pass band with a transmission resonant frequency and a receive resonant frequency. In this manner, the pass band of the antenna tuner can simultaneously provide matching at both a transmission frequency and a receive frequency, when both transmission signals and receive signals are received on the same antenna. The antenna tuner includes a first capacitive element that is coupled to series resonate with the antenna and a low-pass pi network.
