appy New Year from the Antenna Measurement Techniques Association (AMTA) Comer! Hot off of the presses, here's the list (by session number) of the Best Papers from each session from the 2008 AMTA Symposium. The top six papers have been chosen from this list by the AMTA Technical Review Committee, and we look forward to bringing you the best papers from AMTA. We'll have a full write-up of the 2008 Symposium for you in April's edition. 1.

This Issue's Contribution This issue's paper continues the theme from December 2008. It is entitled, "Conical Near-Field Antenna Measurements," and the
authors are Stuart Gregson and Greg Hindman from Nearfield Systems, Inc. The idea behind a conical near-field measurement is fairly simple concept, but difficult to implement in practice. By measuring antenna patterns in the near field on an arbitrary conical surfac'e, antennas mounted on vehicles can be measured more efficiently than with a planar, cylindrical, or spherical surface. In the December 2008 paper, Daniel Leatherwood presented a methodology for conical near-field measurements using the spherical nearfield transfonn as the basis. Stuart and Greg's paper presents a methodology for conical near-field measurements using a modified cylindrical near-field transfonn as the basis. The result is that the measurement surface becomes a right conic frustum. If you compare both papers, it is interesting to note that both authors explicitly state that a particular area of needed additional research is the development of alignment procedures. Steve and I hope you enjoy Stuart Gregson and Greg Hindman's contribution to the AMTA Corner for February 2009.
