Aperturantenne und Radarsystem mit einer derartigen Antenne

摘要

An aperture antenna suitable for a radar system of an automotive vehicle is provided which includes three or more primary radiators (12a-12f) and a feeding circuit (18a,18b). The feeding circuit is designed to supply electromagnetic signals to adjacent two of the primary radiators through discrete feeders (14a-14f) to radiate in phase electromagnetic waves and to extract signals received by the two of the primary radiators separately. This enables the radiation of radar waves over a wider area without increasing the radiation power.
