The Hybrid Tee, also called magic tee, is a combination of a H-plane tee and a E-plane tee. It has four arms:

- The H-(Σ) plane arm, which is in the direction of the H (magnetic) field.

- The E-(Δ) plane arm, which is in the direction of the E (electric) field.

- Two lateral arms. The lateral arms are disposed about an imaginary plane dividing the H- and E-plane arms symmetrically.

The Hybrid Tee is used to split a microwave signal into two even signals and to combine two microwave signals into a single signal.
