Structure of aperture antenna and radar system using same
 An aperture antenna suitable for a radar system of an automotive vehicle is provided which includes three or more primary radiators and a feeding circuit. The feeding circuit is designed to supply electromagnetic signals to adjacent two of the primary radiators through discrete feeders 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.
