The effect of back‐plane distance on the mutual admittance between twin coplanar waveguide (CPW)‐fed slots on conductor‐backed two‐layer substrates with an air bottom layer was investigated. Distances of λ o /6 and λ o /4 yielded significantly increased mutual coupling over the case of no back plane. Measurements supporting the numerical results are presented. © 2005 Wiley Periodicals, Inc.
