We report the complete characterization of microstrip lines at an infrared frequency of 28.3 THz (10.6‐μm wavelength) through modeling, fabrication, and measurement. The transmission‐line parameters of interest can not be directly measured at infrared frequencies—the only measurable quantity is the voltage response of the antenna‐coupled bolometric sensor. We validate the computational approach for transmission‐line parameters by verifying the computed and measured response of the antenna connected to microstrip lines of different lengths. This also allows us to extend these calculations to explore various configurations and identify design trends. © 2008 Wiley Periodicals, Inc.
