Abstract
A new class of broadband symmetrical directional couplers has been investigated. The proposed couplers consist of three coupled-line sections with the middle coupled-line section connected between two identical coupled-line sections in such a way that the coupled and transmission ports of the resulting three-section directional coupler are exchanged in comparison to the well-known three-section symmetrical directional coupler. By choosing coupling coefficients and electrical lengths it is possible to achieve an equal-ripple coupling characteristic. Theoretical analysis has been performed and the properties of the proposed directional couplers are compared to the well-known multisection couplers. The presented theoretical analysis has been verified by the design. (C) 2012 Wiley Periodicals, Inc.
