The novel technique of generalizing complex-to-complex impedance transformers (CCITs) with miniaturization is introduced in this paper. generalized CCITs are designed based on conjugately characteristic-impedance transmission lines (CCITLs) along the Meta-Smith charts (MSCs), resulting convenient design equations. For illustration, a prototype designed, simulated, and implemented an asymmetric ...

analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form greens functions is presented. integral equations are derived from applying the boundary conditions on the radiating patch, across the aperture, and on the microstrip feedline. the computation of space domain greens functions is performed using the closed-form. the solution of the integral equatio...

This article presents the RF characterization results of a large-area MCM-D technology developed within the EU LAP project. Microstrip lines were simulated, designed, and manufactured in several material combinations. Measurements up to 120 GHz showed good coincidence between simulation and reality. Future work is dedicated to filters and antennas in the 77 GHz range.
