Abstract :
A low loss//spl lambda/ slow-wave microstrip transmission line structure is numerically and experimentally investigated. The structure is based on a microstrip line on periodically etched ground plane. Dependency of the slow-wave factor on lattice dimensions is investigated. The slow-wave factor has also been simulated by the FDTD method as numerical verification of the accuracy of the results. Numerical results reveal that the slow-wave microstrip structure can reduce the attenuation//spl lambda/ by 6/spl times/ compared to conventional planar slow-wave structures.
