Abstract

The invention relates to the technical field of antenna array design of millimeter wave security check imaging, and discloses a strip line feed horn antenna applied to millimeter wave security check imaging. According to the strip line feed horn antenna applied to millimeter wave security check imaging, a microstrip line-to-strip line structure is arranged on a printed circuit board, a choke groove is additionally formed between a transmitting antenna array and a receiving antenna array, and the microstrip line-to-strip line structure is used for realizing conversion from a microstrip line toa strip line; and the choke groove is used for suppressing interference signals outside reflection cavities of the transmitting antenna array and the receiving antenna array so as to improve the receiving and transmitting isolation. The strip line feed horn antenna applied to millimeter wave security check imaging has the characteristics of wide band, high efficiency, high isolation, simple structure and high assembly reliability.

Description

technical field [0001] The invention relates to the technical field of antenna array design for millimeter wave security inspection imaging, in particular to a strip line feed horn antenna applied to millimeter wave security inspection imaging. Background technique [0002] The millimeter-wave security imager works in the near-field area of ​​the antenna array. In order to improve the signal-to-noise ratio of the received signal, the transmission power should be increased as much as possible, and the signal isolation between the transceiver antenna arrays should be improved to avoid direct coupling of the transceiver antenna. The chain pre-stage LNA pushes saturation. In order to improve the system integration, the antenna and the RF transceiver module are designed on the same printed board, and the printed line is used to directly connect the power supply, eliminating the need for related connecting cables and RF connectors, effectively reducing the system cost. Currently ...
