New Coplanar Waveguide Based on the Gap Waveguide Technology

A new planar waveguide, coined "Inverted Coplanar Gap Waveguide" is presented. The concept of Gap Waveguides and parallel plate suppression between Perfect Magnetic and a Perfect Electric Conductors is applied to Coplanar Waveguides in order to create a low-dispersion, low-loss transmission line. The combination of an Artificial Magnetic Conductor and channelized top cover allow the propagation of an even coplanar mode with a strong component propagating over the air while solving encapsulation matters without the use of metallic vias. The main theory behind this new concept is presented and supported by FEM simulations on a commercial software package.
