A new six‐port circuit configuration based on branch‐line hybrids and Wilkinson power dividers is presented. The phase difference between two input signals is estimated using this new structure. The results are compared with the most widely used six‐port structures and a notable improvement in broadband performance is shown. Simulations are carried out in order to assess this improvement. © 2004 Wiley Periodicals, Inc.
