Codos 90º compactos óptimamente adaptados en guía de onda rectangular

Abstract

H- and E-plane corners in rectangular waveguide are widely used in microwave systems. An important aspect in the design of these components is to maintain a specified return loss over a wide frequency band. Designs that are compact in size are also required to fulfill space and insertion loss restrictions. In this paper, two families of compact matched corners are considered: the multi-stepped and multi-mitered compact matched corners. Optimum physical dimensions that minimize return losses over the full frequency band are given for the first three members of each family, for de H- and E-plane cases. In addition, a yield analysis of the optimum structures is included. Results are obtained by using the electromagnetic commercial simulator µWave Wizard.
