ABSTRACT:
An antenna module formed with an integrated multilayer substrate having: an antenna with a transmission line; a tuned circuit with a variable capacitance means; a low noise amplifier; and a wave-shaping circuit. The variable capacitance means in the tuned circuit controls a resonance frequency of the antenna by an external control signal being wave-shaped by the wave-shaping circuit, and the antenna outputs a high-frequency output tuned to the controlled resonance frequency to the low noise amplifier directly and then the low noise amplifier outputs the amplified high-frequency output to outside.
