An optimized four-chanel microstrip array at 7T [PDF]

open access: yes, 2006
The microstrip transmission-line (MTL) transmit/receive loop array has been recently developed for MR applications at ultrahigh fields (>4T). In this study, the geometry of transmission-line array, including the substrate thickness and gap between coil ...

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

open access: yesIET 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.

Dispersion Characteristics of the Microstrip Bend at Millimeter Wave Frequencies

open access: yesJournal of Measurement Science and Instrumentation, 2011
The effect of the microstrip bend on the propagation characteristics of a microstrip line was investigated based on the Finite-Difference Time-Domain(FDTD)method.The dispersive characteristics of a microstrip line with a bend are quite different from ...
