Title:
SURFACE WAVE EXCITATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/095934
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a surface wave excitation device. The surface wave excitation device of the embodiments of the present application comprises: a metal waveguide, a coupling part, a feeding part, and a transmission line. The metal waveguide is sleeved over the outside of the transmission line. The coupling part is disposed in the metal waveguide and the metal waveguide and the transmission line are coaxial structures. The feeding part is connected to the coupling part. The coupling part and the transmission line are disposed in parallel. There is a gap between the coupling part and a conductor of the transmission line, such that an electromagnetic wave is transmitted from the feeding part to the coupling part and is coupled to the surface of the transmission line by means of the coupling part, so as to transmit a surface wave. The surface wave excitation device of the embodiments of the present application is used to reduce surface wave radiation loss.
