Abstract

The invention discloses a quick connection type miniature 360-degree circumferential antenna. The antenna comprises a metal disc. A metal monopole cylinder is welded to the back side of the metal disc. The axis of the metal monopole cylinder passes through the center of the metal disc. The antenna also comprises a coaxial line. The external diameter surface of a coaxial line internal conductor of the coaxial line is provided with screw threads. The internal diameter surface of the metal monopole cylinder is provided with screw threads. The coaxial line internal conductor is inserted into the metal monopole cylinder to be in threaded connection and cooperation with the metal monopole cylinder. The antenna further comprises a metal floor. The middle of the metal floor is equipped with an external conductor through hole. The antenna also comprises a dielectric gasket. The dielectric gasket is arranged between a coaxial line external conductor and the metal monopole cylinder. The coaxial line internal conductor penetrates the dielectric gasket.

Description

technical field [0001] The invention relates to antenna technology, in particular to a quick-connect miniaturized 360-degree circumferential antenna. Background technique [0002] Microwave circumferential antennas are mostly used in one-point multiple-access communications, and are widely used in military, aerospace, remote control, and telemetry fields. In the lower frequency band, microwave circumferential antennas mainly include helical antennas, cross-feed antennas, and waveguide slot antennas; with the development of modern communication technology, it is an inevitable trend for communication frequencies to develop to higher bands. In the C-band or higher frequency bands, the wavelength is very short, the above-mentioned antennas are complex in structure, resulting in high processing costs, difficult debugging, and difficult to design the feed structure, making the bandwidth of the antenna narrow; at the same time, the height of these types of antennas exceeds Half-wa...
