Single and double stub matching are techniques used in radio frequency (RF) engineering to match the impedance of a transmission line to a load, minimizing reflections and maximizing power transfer. In single stub matching, a short-circuited stub is added at a specific point along the transmission line, while in double stub matching, two stubs are used, offering greater flexibility in achieving the desired impedance match. These methods involve adjusting the lengths and positions of the stubs to fine-tune the impedance, and they are widely used in antenna feed systems and RF circuit design.

What is a short circuit stub matching?

short circuited stub matching network is a s/c length of transmission line is added in parallel to the main line (physically perpendicular) at the precise location so that its reflected wave exactly cancels out the reflected wave from the load. then all the power is delivered to the load. (since it can not be absorbed by the purely reactive matching network) it thus provides a "perfect Match' at the design frequency and results in more efficient use of the power.
