Abstract

The invention relates to the technical field of microwave antennas and discloses a butterfly microwave antenna and a liquid safety detector. The antenna comprises a shell and an antenna main body fixed at the opening end of the shell, wherein the antenna main body comprises a substrate and radiation basic sheets arranged on the substrate; the radiation basic sheets are arranged in a butterfly modeand form signal transmitting parts and signal receiving parts; the surface, opposite to the shell, on the substrate is coated with a loading ring made of metal; the loading ring comprises an outer ring and an isolation belt arranged in the radial direction of the outer ring; the signal transmitting parts and the signal receiving parts are located at two sides of the isolation belt; and the shellis arranged on the back surface of the antenna main body. according to the butterfly microwave antenna provided in the invention, the signal transmission directivity can be effectively enhanced, the antenna gain consistency is improved, the size is small, the structure is simple, the processing is convenient, the cost is low, ultra wideband transmission of the antenna is realized, the detection range of the liquid detector is expanded, signal interference is reduced, the signal transmission precision is improved, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of microwave antennas, in particular to a butterfly microwave antenna and a liquid security detector equipped with the butterfly microwave antenna. Background technique [0002] In order to provide people with a better travel environment, liquid detection has become more and more common in security inspection procedures in airports, subways, shopping malls and other places, and the demand for liquid detectors has gradually increased. [0003] The microwave liquid detector that appeared in recent years uses microwave detection technology to detect the safety of liquids. It is famous for its high accuracy and good safety performance, and has become the development direction of portable liquid detectors. The microwave is generated by a microwave oscillator, and the oscillation signal is guided through the waveguide, and then emitted through the transmitting antenna, and the return signal is received through the...
