Abstract :
The current distribution along the arms of tripoles arranged on two equilateral triangular lattices has been computed and shown to have a simple cosinusoidal form. Calculated and measured transmission curves agree closely and give band spacings ¿2:1. The crosspolar performance in a 45°-incidence diplexer is lattice-dependent.
