Investigation and design of rectangular waveguide using composite right / left handed transmission line (CRLH-TL) structure for microwave and communication consumer applications

Control and manipulation of electromagnetic waves is at the heart of many industries from wireless communication, internet and optical data storage to imaging and microwave applications. Progress in metamaterial technologies places challenging demands on material properties and therefore structured electromagnetic materials. The development of composite right / left-handed transmission lines (CRLH-TLs) has received considerable attention due to the unique propagation characteristics. In this paper, a new rectangular waveguide using CRLH-TL array structure has been introduced and used as an alternative to the traditional rectangular waveguide. The analysis and investigation are done by a commercial software. The good agreement between the theoretical expectation and the simulation results is observed and analyzed. Finally, the application of the selected proposed CRLH-TL array was examined in rectangular waveguide. The proposed CRLH-TL waveguide design has been fabricated and the measured S-parameters of the proposed structure can be analyzed with network analyzer to demonstrate the excellent performance and verify the design operational for microwave and communication consumer applications.
