Abstract
An antenna apparatus includes a dielectric substrate, a base plate, an antenna unit, and a reflecting unit. A plurality of conductor patches are structured to resonate, at an operating frequency of the antenna unit, in a resonating direction which is different from a polarization direction Dan of a radio wave transmitted and received by the antenna unit.
Claims20
An antenna apparatus mounted in a bumper of a vehicle, the antenna apparatus comprising:
- a dielectric substrate;
- a base plate provided on the dielectric substrate and configured to serve as an antenna ground surface;
- an antenna unit provided on a surface of the dielectric substrate, and having an antenna pattern configured to serve as an antenna array;
- and
- a reflecting unit arranged to surround the antenna unit, including a plurality of conductor patterns serving as a reflector,
- wherein each of the plurality of conductor patterns has a size smaller than an effective wavelength, at a preset operating frequency of the antenna unit, and is structured to resonate in a resonating direction different from a polarization direction of a radio wave transmitted and received by the antenna unit.
