Abstract
An antenna apparatus has an antenna unit. The antenna unit transmits or receives a probe wave made of an electromagnetic wave. A magnet is disposed at a location through which the probe wave to be received by the antenna unit passes. The magnet works to generate a magnetic field along a direction in which the probe wave propagates. A polarizing filter is arranged on an opposite side of a magnetic body to the antenna unit. This minimizes the interference between an emitted wave and a reflected wave created by a cover, such as a bumper, regardless of the configuration of the cover.
