Abstract:
A directional coupler operable at microwave and RF frequencies. Embodiments of directional coupler includes a main transmission line supporting transverse electromagnetic (TEM) or quasi-TEM wave mode propagation. A coupled transmission line supports TEM or quasi-TEM wave mode propagation. The coupled transmission line is adjacent to and oriented at an angle with respect to the main transmission line. A coupling hole is formed through conductive shielding between the main and coupled lines, the coupling hole formed at an intersection region between the main and coupled lines. The angle is nominally 60 degrees for optimal directivity and isolation.
