In this paper we present a synthetic waveguide integrated in a commercial BiCMOS back-end-of-line, employing artificial dielectrics (ADs) to reduce the component size. The AD is realized by employing floating pillars using the various layers available in the technology, thus fulfilling metal density rule and boosting the effective permittivity of the host medium (i.e., SiO2) to 12.5. The impact of...
Microwave broadband wide-scan antenna arrays are typically implemented resorting to vertical arrangements of printed circuit boards (PCBs). Here, we propose a planar solution realized with a single multi-layer PCB, with consequent reduction in cost and complexity of the array. It consists of an array of connected slots backed by a metallic reflector and loaded with superstrates. Artificial dielectric...
This contribution presents the development of an integrated power combiner in Bi-CMOS technology employing artificial dielectric layers (ADLs) at submillimeter wave frequencies. The power is gathered from frequency multiplier chains into a single waveguide which is loaded with ADL in order to reduce the structure footprint.
