Abstract

The embodiment of the present application discloses a surface wave excitation device. The surface wave excitation device in the embodiment of the present application includes: a metal waveguide, a coupling part, a feeding part and a transmission line, the metal waveguide sleeve is placed outside the transmission line, the coupling part is placed inside the metal waveguide, and the metal waveguide It is a coaxial structure with the transmission line; the feeding part is connected to the coupling part, and the coupling part is arranged in parallel with the transmission line, and there is a gap between the coupling part and the conductor of the transmission line; so that the electromagnetic wave Propagated from the feeding part to the coupling part, coupled to the surface of the transmission line through the coupling part to transmit the surface wave. The surface wave excitation device in the embodiment of the present application is used to reduce surface wave radiation loss.

Description

Technical field [0001] The present application relates to the field of communications, and more particularly to a surface wave excitation device. Background technique [0002] With the development of wireless communications, the long distance transmission of RF electromagnetic energy can be performed using antennas, for example, signals from the transmitter to the transmitting antenna or from the receiving antenna to the receiver are completed by the transmission line, and the transmission line includes waveguide and Binary, etc., where the waveguide or coaxial transmission is used, which is very cumbersome and expensive, and the use of surface waves will overcome these disadvantages on the single conductor transmission line, and the single conductor transmission line has simple structure, cheap, lightweight Attenuation is small. [0003] Currently, as a key component in the surface wave wireless communication system, due to the poor performance of the surface wave excitation dev...
