Broadband rectangular‐to‐ridge‐to‐T‐septum waveguide transformers

Abstract

Broadband transformers from rectangular to T‐septum waveguides are presented. By utilizing both ridge and T‐septum waveguide sections in the transformer design, the thicknesses of the ridge and the T‐septa can be kept constant, which simplifies fabrication. The three‐ and four‐section designs achieve relative bandwidths of 57% and 72%, respectively. Both designs are verified through computations with commercially available field solver software. © 2004 Wiley Periodicals, Inc.

“…more than ten percent. (For verification of the code by HFSS, the reader is referred to [10].) Several Ku-band satellite applications utilize the 11.7 -12.5 GHz and 17.3 -18.1 GHz frequency ranges.…”

“…Both techniques have been previously verified by HFSS, e.g. [9], [10]. Optimization is based on a MiniMax routine, e.g.…”
