MICROSTRIP PATCH ARRAY RADAR ANTENNA FOR HEAVY EQUIPMENT VEHICLE

摘要

The present invention relates to an antenna mounted on a heavy equipment vehicle and capable of detecting an object close to the rear surface by checking a short distance of about 30 m with a detection range of 140 degrees or more using a wide beam width. The present invention provides a transmitting antenna comprising a pair of patch array portions vertically arranged with a plurality of radiation patches connected to each other by a feed line and having a power distribution portion for feeding power between the patch array portions; And a receiving antenna provided in a shape in which the transmission antennas are opposed to each other with a 180-degree phase difference so that the interval between the center lines of the radiation patches is a half-wave length, and a radar antenna for a near- .
