US Patent 10957973 Antenna module

The present disclosure improves, in an antenna module, the isolation characteristic between an output signal from an antenna and an input signal. An antenna module includes a dielectric substrate having a first surface and a second surface, an antenna formed on the first surface, a radio frequency element configured to supply a radio frequency signal to the antenna, and a signal terminal formed into a columnar shape using a conductive material. The signal terminal is connected to the radio frequency element by a wiring pattern in the dielectric substrate. The signal terminal is disposed outside an excitation region generated in an excitation direction of an output signal.
