DUAL ANTENNA APPARATUS

摘要

This dual antenna apparatus has a receiving antenna, which has an area of a first surface as a first opening area, said first surface being orthogonal to incident waves, and a transmitting antenna, which has an area of a second surface as a second opening area, said second surface being parallel to the reflection direction, i.e., the transmitting direction. The transmitting antenna and the receiving antenna share a part of the structures thereof.
