Abstract
A transition from a planar transmission line to a waveguide has a planar transmission line patterned onto a glass substrate. A mode transformer on the substrate is electrically connected to a transmission line and converts a transverse electric or quasi-transverse electric mode signal carried by the transmission line to a waveguide mode signal. A combination of a first extension of the substrate and a dielectric portion having some depth makes up a first impedance matching element . A second impedance matching element is a combination of a second extension of the substrate and a dielectric portion having another depth greater than the first depth. The aperture created by the second impedance matching element launches an RF signal into the air for use as a wireless communication signal. Also disclosed is a method for optimizing a transition according to the teachings of the present invention for alternative dimensions and dielectrics.
