Design of Substrate Integrated Waveguide Duplexer for X-band Application
摘要
Substrate integrated waveguide represent a promising solution of designing performing circuits with a low-cost, high-quality factor and it is easy to be integrated with other planar circuits. This paper presents the design of a microstrip diplexer through a substrate-integrated waveguide. The diplexer consists of two independently designed SIW circular cavity filters combined together using a T-junction with center frequencies of 9 and 10 GHz, respectively.
