Tunable Via-free Microstrip Composite Right/Left-Handed Transmission Lines Using MEMS Technology
نویسندگان
چکیده
In this contribution a tunable via-free microstrip composite right/lefthanded transmission line (CRLH-TL) is designed and simulated. To add tunability RF MEMS elements are implemented in the interdigital capacitors and stub inductors, which match the line impedance during tuning. The via-free design enables easy and low-cost fabrication. Additionally, tunable zero-order resonators (ZORs) using two and three-cell CRLH-TL units, which have the resonant frequency tuning capability, are designed and simulated to verify the size-independent characteristic of ZORs.

The propagation and radiation properties of dual composite right/left-handed (D-CRLH) transmission line metamaterials are presented, and validated experimentally with a 1D microstrip prototype. In its fast-wave regime, this structure operates as a leaky-wave antenna capable of backfire-to-endfire radiation scanning with beam squinting smaller than that of conventional CRLH (C-CRLH) antennas. It...
