A broadband microstrip-to-slot-line transition

Abstract

This paper presents a double slot-line–microstrip transition employing a 90° cross over them. Using radial stubs at the crossover between the transmission lines, an insertion loss of less than 1.3 dB was measured (0.65 dB per transition) over the 3–15 GHz range. The transition is simulated using a commercial electromagnetic finite-element simulator. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 18: 339–342, 1998.
