Abstract
The present invention disclosed an apparatus and method for receiving a plurality of broadcasting signals. The apparatus comprises: a control circuit for generating an analog control voltage signal according to a frequency-voltage look-up table and a desired frequency; an antenna module comprising an antenna and an antenna resonant control circuit comprising a voltage-controlled capacitor being controlled by the analog control voltage signal, wherein the antenna resonant control circuit comprises a voltage-controlled capacitor to control the bandwidth received by the antenna according to the analog control voltage signal; a tuner for tuning a broadcasting signal received by the antenna to generate an output signal; and a demodulator for demodulating the output signal of the tuner.
