Quad-Band Resonator Depends on CRLH/D-CRLH Structures (.PDF Download)

Quad-Band Resonator Depends on CRLH/D-CRLH Structures (.PDF Download)

This article presents the design and implementation of a compact quad-band bandpass filter based on coupling between via-free dual-composite right-/left-handed (D-CRLH) and composite right-/left-handed (CRLH) microstrip structures. The filter can be used for multiband wireless applications like WiMAX and WLAN, as well as other high-frequency applications. Its topology results in four bands with highly selective, sharp bandpass responses.

A design is introduced to realize a quad-band resonator. Also presented are the equivalent circuit model, an analytical study, and simulation and fabrication measurement results.
