A Shielding Structure of Microstrip Planar Antenna Microwave Sensor

Abstract

The invention discloses a shielding structure of a microwave sensor of a microstrip planar antenna, the upper end of the mounting seat is fixedly connected with a protective cavity, the inner bottom end of the protective cavity is fixedly connected with a plurality of first sliding grooves on the mounting seat, a plurality of balls are rotatably connected to the inside of the plurality of first sliding grooves, The first fix seat is designed, A movable rod and a second telescopic cavity are elastically connected to the inside of the corresponding fixing seat through a first spring, Thus, the microstrip antenna and the microwave antenna with different sizes are effectively fixed, and through the design of the fan, the first air suction port and the second air suction port, the temperature generated by the operation of the internal components of the protective cavity is effectively discharged to the outside of the protective cavity, and the heat dissipation is effectively assisted, so that the device is more safe and practical.

Description

Technical field: [0001] The invention belongs to the technical field of microwave sensors, in particular to a shielding structure of a microstrip planar antenna microwave sensor. Background technique: [0002] A microwave sensor is a device that uses microwave characteristics to detect some physical quantities. Its shape is mostly a rectangular structure. The shielding structure is a device that ensures signal transmission between internal components and isolates external signals. The traditional shielding structure adopts a box-shaped structure design. , when the structure is used, it is necessary to choose a shielding box that matches the size of the microstrip planar antenna microwave sensor of the relative size, which is insufficient in usability and improved, and when the traditional shielding structure is used in the microstrip planar antenna microwave sensor, its shielding The inside of the box structure is easy to respond to the use of related components for too long...
