Probe apparatus capable of realizing transmission of dual-polarized signal by adopting dielectric waveguide

Abstract

The invention discloses a probe apparatus capable of realizing transmission of a dual-polarized signal by adopting dielectric waveguide. The probe apparatus comprises a base and a dielectric rod; oneend of the dielectric rod is mounted on the base while the other end of the dielectric rod can be inserted in a rectangular waveguide interface of a single-polarized microwave parabolic antenna; an anti-leakage layer for preventing external leakage of the dual-polarized signal is formed on the outer wall of the dielectric rod; a circular waveguide interface for allowing the dual-polarized signal to pass through is formed in the base; and the dielectric rod provides a dual-polarized signal transmission channel. By virtue of the probe apparatus, the problem that the dual-polarized signal cannotbe transmitted by a circular rectangular transitional section in the single-polarized microwave parabolic antenna is solved; and the purpose that the single-polarized microwave parabolic antenna can transmit the dual-polarized signal without considering an internal feed source pipe interface of the single-polarized microwave parabolic antenna is realized.

Description

technical field [0001] The invention belongs to the communication field, and relates to a probe device for realizing dual-polarization signal transmission by using a dielectric waveguide. Background technique [0002] Antenna is an extremely important component in a microwave communication system, its main function is to radiate electromagnetic signals to space and receive electromagnetic waves from space. Among them, the parabolic antenna is the most commonly used device for point-to-point microwave P2P (point-to-point) communication. It is characterized by linear polarization transmission, high gain and strong directivity. A single-polarized microwave parabolic antenna radiates into space and receives single-polarized signals (see figure 1 ); the dual-polarized microwave parabolic antenna can radiate and transmit dual-polarized signals (see figure 2 ); realize the same-frequency orthogonal polarization frequency multiplexing technology, that is, transmit two channels of...

Problems solved by technology

[0005] If it is necessary to upgrade the single-polarized antenna to a dual-polarized antenna, the existing solutions in the industry are to remove the original single-polarized antenna and replace it with a dual-polarized antenna, or remove the circular-square transition section of the single-polarized antenna (see figure 1 ), the OMT is directly connected to the feed tube to upgrade to a dual-polarized antenna, but if there is a situation where the interface of the feed tube is not uniform, it will cause the OMT to need multiple interfaces for adaptation, only in a single antenna manufacturer In addition, there is a certain degree of operability in the scene where there are few historical changes in the interface of the feed pipe, because the antenna is a passive device, and the type and version of the antenna cannot be identified in advance, so all OMT interfaces can only be prepared at the same time to ensure the success rate of the transformation

In addition, after the antenna has been used in the outdoor environment for many years, the fasteners such as screws may rust and the round-to-square transition section cannot be disassembled. There is a lack of a single-polarized antenna that is compatible with a variety of internal feed tube interfaces and easy to operate. Upgrade to dipole Transformation plan of the antenna
