摘要：

A quad-band rat-race coupler is presented based on the Generalized Negative Refractive Index Transmission Line (GNRI-TL) unit cell. The methodology for designing unit cells that account for the host transmission line is first described and then deployed for the design and fabrication of a quad-band unit cell operating at four widely used frequency bands. The measured results are compared to the simulated ones yielding reasonable agreement. Finally, a quad-band rat-race coupler is subsequently designed based on the unit cell measurements and the simulated results are presented.
