7.5.2 H-Plane Tee
When a short piece of waveguide is fastened perpendicular to the narrower
wall of a waveguide, the resulting three-port junction is a Calledean H-plane
tee. The perpendicular arm is usually the input arm and the other two arms
are in shunt to the input. For this reason, this tee is called a shunt tee. Power
fed into the input arm splits equally and in phase in the other two arms. If
two signals of equal amplitude and the same phase are fed into the two arms
of this tee, these will combine and add in the input arm. This tee along with
the division of elds for different locations of inputs and appeara ...
