Description

Technical Field

[0001] The utility model relates to the technical field of antenna feeder stable connection, in particular to an antenna feeder stable connection device. Background Art

[0002] Antenna feeder refers to the transmission line that connects the antenna to the transmitter and receiver to transmit radio frequency energy. It is required to have good impedance matching with the antenna, small transmission loss, small radiation effect, sufficient bandwidth and power capacity. There are parallel double lines, coaxial lines, microstrip lines, and waveguides. Usually, parallel double lines and coaxial lines are used as feeders for wire antennas; microstrip lines and coaxial lines are used as feeders for microstrip antennas; waveguides are used as feeders for reflector antennas and horn antennas. Electronic technology is used to measure the performance of radio communication systems and their components, parts, equipment, electromagnetic environment, and radio materials. Its parameters include electromagnetic medium, frequency, power, attenuation, impedance, standing wave, field strength, phase, waveform, spectrum, etc. The instruments used are: signal generator, frequency meter, power meter, impedance meter, standing wave meter, field strength meter, spectrum analyzer, test receiver, network analyzer, oscilloscope, integrated circuit tester, transmission comprehensive tester, etc. When measuring small signals, interference caused by stray radio, power and ground wires, radio coupling, etc. should be prevented. This type of measurement requires good matching and is usually performed in a shielded room. In existing antenna feeder connectors, after installation, the connector can often be rotated by hand even if a wrench is used to tighten the connector, resulting in poor contact between the connector and the feeder, which makes the entire signal transmission process intermittent. It is difficult to find the specific cause when troubleshooting the problem, which increases the workload and reduces work efficiency during replacement and maintenance. Therefore, we propose a stable connection device for antenna feeders. Utility Model Content
