Design formulas for the development of an uncommon 180°hybrid working in two distinct frequency bands are provided. In particular, the design formulas of a lumped-element (LE) rat race, starting from a conventional transmission-line version, are obtained. Moreover, in order to generalize the approac

Abstract
A monolithic 20 GHz 90° hybrid is introduced. The hybrid design is based on a lumped‐component approach that makes use of planar coupled inductors. The hybrid model and design technique are discussed. Experiments validating the structure are reported. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 392–394, 2001.

A new dual-band antenna that uses coplanar wa¨eguide ( ) CPW structures and which is suitable for MMIC applications is presented. The new design offers the flexibility of changing the frequency ratio between the upper and lower frequency bands, as well as designing for a single, but wide band. Two a
In this letter, we propose a new concept for a self-switched time shifter. The structure is theoretically in¨estigated by means of an analytical approach and computer simulation. The electrical performances of the proposed configuration are compared with those of a con¨entional single-pole double-th
