Design & characterization of a coaxial cell for miniature H-field loops calibration

For measuring intense, pulsed electromagnetic fields in confined areas, a need existed for H-field probes with bandwidths up to 3GHz. This paper first presents the design and construction of small, precision Moebius loops, capable of measuring short field pulses with sub-nanosecond rise time. Then, the design, construction details and calibration of a slotted coaxial test line are described, for a precise characterization of these H-field probes.
