Abstract

The invention relates to a three-transmitting four-receiving wide beam antenna, which at least comprises a dielectric substrate and a metal ground plate arranged on one side surface of the dielectricsubstrate, wherein the other side surface of the dielectric substrate is further provided with a transmitting unit and a receiving unit, the transmitting unit includes three transmitting linear arrays, both sides of each transmitting linear array are provided with two parasitic linear arrays, and the three transmitting linear arrays are distributed at equal intervals along the transverse directionof the dielectric substrate; the receiving unit includes four receiving linear arrays, both sides of the four receiving arrays are further provided with parasitic linear arrays, and the four receiving linear arrays are distributed at equal intervals along the transverse direction of the dielectric substrate; and both the transmitting linear arrays and the receiving linear arrays are connected with a feed network. The antenna of the invention aims to broaden the beam and improve the resolution of corner radar.

Description

Technical field [0001] This application relates to the technical field of automobile assisted driving, and in particular to a three-engine four-wide beam antenna. Background technique [0002] With the rapid development of the automobile industry, the automobile industry has entered the stage of autonomous driving on the road of pre-research of intelligent driving. Intelligent driving is the development trend of the future automobile field. However, the safety issues in intelligent driving are also particularly important. Among the many sensors, millimeter-wave radar is currently the focus of major electronic devices and automobile manufacturers. At present, most of the commercial radars in mass production are forward or backward radars, which are used to detect front and rear mid-range and forward long-range targets; while video and infrared radars appearing on the market can only detect short-range or ultra-short-range targets. Its detection range is short and it is easily aff...
