Abstract

The invention provides a long-range antenna, an antenna array and a radar using the antenna array. The long-range antenna comprises: a radiation unit for transmitting / receiving electromagnetic wave signals and coupling the electromagnetic wave signals transmitted / received by each radiation unit through a feed line; a feed line, which includes a feed line end group, wherein the feed line end groupcomprises a plurality of feed line ends, and each of the feed line ends is disposed at a position in contact with the radiation unit and used for connecting the radiation unit and the feed line; and aconnecting line group, which includes a plurality of connecting lines, each of which is used for connecting two adjacent feed line ends. The relative angle between the feed line end and the connecting line is non-vertical and / or non-horizontal. The length of the connecting line is longer than the interval length between the adjacent feed line ends. According to the invention, narrow frequency band response and long-distance coverage can be realized without increasing the area.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a long-distance antenna, an antenna array and a radar using the antenna array. Background technique [0002] Antenna array is the most common transmitting and receiving mechanism used in radar systems. At present, the antennas used in millimeter-wave radar are mostly series-fed antenna arrays. [0003] Such as Figure 1-Figure 2 As shown, the electromagnetic wave signal is coupled and received from the radiator 1, and at the same time, through the slow wave action of the material 3 and the reflection of the ground 6, the high-frequency current is transmitted to each node in the radiator 1 through the feeding line 2, and the radiator In 1, the low side lobe effect of the antenna is realized through the design of different current intensities, and the high-frequency current passes through the impedance transformation section 4, and the transmitted energy is maximized...
