Abstract
An antenna module includes a first substrate, a power supply circuit, and an external connection terminal. Transmission lines that transmit a control signal, an intermediate frequency signal, and a Local signal and filter circuits are provided between the power supply circuit and the external connection terminal.
Claims20
An antenna module comprising:
- a radiating element that emits a radio wave in a first frequency band;
- a first substrate at which the radiating element is disposed;
- a power supply circuit that is connected to the radiating element;
- an external connection terminal that is electrically connected to an external substrate;
- a transmission line that is connected between the external connection terminal and the power supply circuit and that transmits a control signal and an intermediate frequency signal from the external connection terminal to the power supply circuit, the control signal being output from the external substrate and received at the external connection terminal, and the intermediate frequency signal corresponding to the radio wave emitted from the radiating element and received at the external connection terminal;
- and
- a filter circuit that is provided at the transmission line at a position between the external connection terminal and the power supply circuit and that blocks a signal in a second frequency band,
- wherein the second frequency band is lower than a frequency band of the intermediate frequency signal and higher than a frequency band of the control signal.
