Abstract:
1. A probe for sampling electromagnetic energy in a circuit comprising: a mating portion for mating broadside with an electromagnetic energy transmission media in the circuit, the mating portion including a coupling conductor for retrieving a sample of the electromagnetic energy in the electromagnetic energy transmission media; and a correction device for correcting impedance mismatch resulting from mating the mating portion with the electromagnetic energy transmission media of the circuit, wherein the coupling conductor is a quarter wavelength conductor, and the correction device includes a first quarter wavelength dielectric overlay positioned on a first side of the coupling conductor, and a second quarter wavelength dielectric overlay on a second side of the coupling conductor, the combination of the coupling conductor, the first quarter wavelength dielectric overlay, and the second quarter wavelength dielectric overlay forming a three quarter wavelength overlay that overlays the electromagnetic energy transmission media as a broadside coupler when the mating portion is mated with the electromagnetic energy transmission media.
