The H-plane Tee junction is a three-port microwave network characterized by symmetry and the condition that its third port (the side arm) is perfectly matched to zero reflection ($S_{33}=0$). Through the application of Scattering Matrix theory, specifically utilizing unitary matrix properties for lossless reciprocal networks, it is derived that the isolation between input ports requires a specific phase relationship where $S_{12} = -S_{11}$ and all magnitudes are equal to $\pm 1/\sqrt{2}$. This configuration establishes strict amplitude division rules essential in microwave engineering for power splitting applications.
