Abstract
The problem of miniaturization of coupled-line directional couplers designed as a connection of tightly-coupled and uncoupled sections has been comprehensively investigated for the first time.It has been proven that in such couplers the stronger coupling is available in the structure, the greater miniaturization is achieved. A novel approach allowing for theoretical analysis of such couplers has been proposed. Moreover, a special case has been considered, in which couplers are designed with the use of a single section of uncoupled lines placed in the middle of a tightly-coupled section. The proposed approach has been utilized for derivation of theoretical limits describing the maximum achievable minimization of the overall electrical length of couplers designed as a connection of coupled and uncoupled lines. The theoretical analyses have been confirmed by the measurements of two different directional couplers designed with the use of the proposed approach. (C) 2012 Wiley Periodicals, Inc.
