Abstract

This paper describes the new tabletop millimeter wave extrapolation range which will provide on-axis gain services up to 110GHz. A discussion of the extrapolation measurement method [1], as presented at the Antenna Measurements Techniques Association (AMTA) in 1999, is the basis for much this paper. The extrapolation method for determining gain of directive antennas at quasi-near-field distances is based on a generalized three-antenna approach. It has been used at NIST for more than twenty years to calibrate antenna gain standards up to 20 GHz to within 0.1 dB and up to 50 GHz to within 0.15 dB. The basic theory, description of the measurement system, data acquisition procedure, and measurement results for three antennas at 94 GHz will be presented.
