An antenna module to be provided to a vehicle includes: an array antenna configured to form a beam directed from an aperture provided in an exterior body panel of the vehicle, toward a vehicle outside; and a housing holding the array antenna in a vehicle inside.

Antenna module and vehicle

A planar antenna includes: a radiating element; a flexible dielectric film portion; a power feeder line provided for the dielectric film portion, and configured to feed power to the radiating element; a first ground conductor facing against the radiating element; and an antenna base having a dielectric layer disposed between the radiating element and the first ground conductor. The dielectric film portion extends from a side surface of the antenna base. The dielectric layer is thicker than the dielectric film portion.

Planar antenna and wireless module

An antenna moduleincludes one antenna basehaving a radiation surfaceinclined relative to an opening planeat which a radomeis attached, and another antenna basehaving a radiation surfaceinclined in a direction different from the one antenna base

A compensation apparatus compensates a quadrature-demodulated signal output from a quadrature demodulatorthat performs quadrature demodulation by using a signal of a carrier frequency fc, by removing an image component caused by the quadrature demodulatorfrom the quadrature-demodulated signal. The compensation apparatus includes a signal generatorthat generates a reference signal having a predetermined bandwidth in a reception band, and provides the reference signal to an input side of the quadrature demodulator. The reference signal includes a frequency band that is biased to either a higher-frequency side or a lower-frequency side with respect to the carrier frequency.
