Resonance phenomena and power loss in conductor-backed coplanar structures

Resonances and associated power loss which occur in conductor backed coplanar transmission lines (CPWs) at selected frequencies have been investigated by experiment and by three-dimensional (3-D) EM simulations from 1 to 230 GHz. It is found that a substantial part of the incident power is lost by reflection and radiation. The resonance frequencies are predictable by patch antenna theory.
