Abstract :
Microstrip in-line and offset gap discontinuities in both laterally open and fully open environments are analyzed using a deterministic spectral-domain method. The analysis includes the effects of space-wave and surface-wave radiation and coupling in the case of fully open environments. It also includes the effects of LSM (longitudinal-section magnetic) and LSE (longitudinal-section electric) wave radiation and coupling in the case of laterally open environments. In the case of laterally open environments, the effect of cover height is investigated. The analysis includes the effects of two-dimensional, two-component current flow on the conductors. It is shown that a conducting cover can actually increase overall transmission loss despite preventing space-wave radiation.<>
