Strongly Enhanced Sensitivity in Planar Microwave Sensors Based on Metamaterial coupling

, 2017
Limited sensitivity and sensing range are arguably the greatest challenges in microwave sensor design. Recent attempts to improve these properties have relied on metamaterial- (MTM-) inspired open-loop resonators (OLRs) coupled to transmission lines (TLs)

Iterative synthesis method for high‐directivity symmetrical stepped‐impedance microstrip parallel‐line coupler

IET Microwaves, Antennas & Propagation
Traditional quarter‐wavelength parallel‐line couplers (QWPLC) in microstrip form suffer heavily in low directivity because of unbalanced even‐mode and odd‐mode phase velocities.
