Abstract :
The operation of E-plane waveguide circulators is explained and verified by eigenvalue measurements. Besides the reverse type circulator, which is usually realized but has inherently small bandwidth, a forward type operation has been found with good potentials for broad-band performance. A model at 10 GHz showed 20 % bandwidth at 20 dB isolation without using external transformers.
