Title:
ANNULAR SURFACE WAVE TRANSMISSION LINE FED BY COPLANAR WAVEGUIDE
Document Type and Number:
WIPO Patent Application WO/2019/184270
Kind Code:
A1
Abstract:
Disclosed is an annular surface wave transmission line fed by a coplanar waveguide, comprising a dielectric substrate, two coplanar waveguides, two transition segments, and an annular surface plasmon structure. The two coplanar waveguides, the two transition segments, and the annular surface plasmon structure are disposed on the same layer of the dielectric substrate. The two coplanar waveguides and the two transition segments are in a one-to-one correspondence, both the two coplanar waveguides and the two transition segments are symmetrically disposed, and each of the coplanar waveguides is connected to one end of the annular surface plasmon structure via a corresponding transition segment. The present invention can transmit an electromagnetic wave in a surface plasmon mode at a microwave frequency, has the features of a simple structure, wide working bandwidth, convenient processing, and high integration degree, and has great application value in microwave integrated circuits and communication systems.
