Improved Design for Symmetrical Six-Port Microstrip Coupler (Based on Double-Ring-with-Star Topology)

S. P. Yeo, B. Tan and E. H. Kwek

Page 1074.

Abstract:

Other researchers have designed a symmetrical six-port microstrip coupler that yields a bandwidth of 7%. It has been found in this paper that a change of the design topology allows the coupler's bandwidth to be increased. A simple-to-use computer model of the double-ring-with-star prototype has also been developed and tests have confirmed that good agreement can be expected between the predicted and measured results.
