Radio Science Bulletin 313 - June 2005 - URSI

Leland Bowen, Everett Farr, Dean Lawry, and ScottTyo describe the design of a very compact impulse-radiating(ultra-wideband) antenna in their paper. The design isspecifically intended for use on a low-Earth-orbit satellite.One of the interesting aspects of this paper is that it tracesthe development of the ultimate design for the antennathrough three evolutions, with measured data and experiencewith the mechanical-design aspects being presented foreach. The antenna uses a collapsible design, with a metalliccoveredfabric forming the surface of the reflector. Thedescriptions of the development of the mechanism fordeploying the antenna, as well as for supporting the reflectorsurface, provide interesting insight into what is necessaryfor space-based applications. The final resulting antennaachieved many of the design goals, and is capable ofsupporting either single- or dual-polarization operation.Our Reviews of Radio Science papers will resumewith the next issue of the Bulletin.Best Wishes for the New Year!This will reach our readers in December, or shortlyafter the new year. At the end of one year and the beginningof the next, there are many opportunities to reflect on whatwe have received in the year past. I’m thankful for the honorand fun of being able to work with all of the wonderfulpeople associated with URSI, and particularly, with theBulletin: Paul Lagasse, Inge Lievens, Inge Heleu, JohnVolakis, Phil Wilkinson, our Associate Editors, and theURSI Board (this time, both new and old). These people doa wonderful job, are very tolerant of an Editor’sshortcomings, and are very professional. Thank you!I wish all in the radio science community a mosthappy, healthy, safe, and prosperous New Year!Subscribe now !If you were not able to attend the URSI General Assembly inNew Delhi (India) last October, please fill in the form on theback cover of this issue and pay your Radioscientist fee as soonas possible with VISA or MASTERCARD, so that you willreceive the Radio Science Bulletin in the next triennium also.Please note that we do not accept cheques.4TheRadio Science Bulletin No 313 (June, 2005)
