The Anglet: A Novel Singlet Building Block Subclass and Alternatives for E-Plane Cross-Coupled Filter Design

Standard technologies for mid- to high-frequency-range circuits generally come in the form of microstrip and coplanar waveguides. Inherently, these types of circuits provide attractive attributes, such as low cost, simple fabrication, and a high-degree of miniaturization and planarity. However, for high-performance and mission-critical applications, such as satellite constellations, broadcast communications, and remote sensing, these high-end circuits require a much more robust transmission line technology, such as metallic waveguides, which can accommodate higher operational frequencies and wider bandwidths with low signal loss and high-power handling.
