Beschreibung: <jats:title>Abstract</jats:title><jats:p>This article presents the methods of broadband axial feeding of a Fabry–Perot resonator. The resonator was originally designed with the radial excitation for the absorption measurement in the frequency band ranging from 18 to 80 GHz. If the frequency stays below ∼26.4 GHz, the excitation of resonator is less satisfactory, since at the frequency in question, the value of Fresnel number of resonator drops to one. For the broadband measurement of gaseous samples' emission spectra, the excitations for frequencies lower than 26.4 GHz were analyzed using the capacitive coupling and two newly proposed couplings. © 2011 Wiley Periodicals, Inc.
