Abstract
An occupancy detection system for at least one vehicle seat includes: an antenna arrangement having an antenna; a control device that applies a radio-frequency transmission signal to, and receives a response signal from, the antenna arrangement; and a transmit array having a plurality of structured metallic layers disposed above each other and extending laterally, each two neighbouring metallic layers isolated from each other by an intermediate dielectric layer. The antenna arrangement transmits a radio-frequency transmission field through the transmit array onto the vehicle seat in response to the transmission signal and receives a radio-frequency response field through the transmit array to generate the response signal. The transmit array is adapted to refract at least one of the transmission field and the response field. The transmit array has a receive section that focuses a response field from a position of a vehicle seat to a position of a receive antenna.
