Abstract

The invention provides an ultra-wideband radar antenna, comprising a transmitting component and a receiving component. The transmitting component comprises a transmitting metal back cavity 1 having an upward opening, a transmitting insulating medium plate 16, and a transmitting antenna 2; the transmitting insulating medium plate 16 covers the upward opening of the transmitting metal back cavity; the transmitting antenna 2 is arranged on the surface of the transmitting insulating medium plate. The receiving component comprises a receiving metal back cavity 7 having an upward opening, a receiving insulating medium plate 17, and a receiving antenna 16; the receiving insulating medium plate 17 covers the upward opening of the receiving metal back cavity; the receiving antenna 16 is disposed on the surface of the receiving insulating medium plate. The transmitting metal back cavity 1 is fixedly connected with the receiving metal back cavity 7 through a metal material. The transmitting antenna 2 and the receiving antenna 6 are coplanar. The ultra-wideband radar antenna is a planar butterfly antenna having the metal back cavities; the ultra-wideband radar antenna is smaller in overall size, well linkable to the wall and good in wide-band characteristic.

Description

technical field [0001] The invention relates to the technical field of radar in the electronic industry, in particular to an ultra-wideband radar antenna. Background technique [0002] UWB radar technology is a radar detection method with good resolution and penetration depth, which can effectively non-invasively detect hidden targets in or behind walls. In municipal engineering, construction industry quality inspection, road disease and other industries, UWB radar technology can work efficiently and accurately, which helps to improve the quality and reliability of engineering construction, and has great economic value. Especially in buildings, UWB radar technology is very useful in the quality inspection and hidden danger elimination of water and electricity wiring, steel bar pouring, etc. [0003] Ultra-wideband radar technology emerged in the 1970s and 1980s. my country's research started relatively late, focusing on theoretical research and laboratory prototype developm...
