FD-06: Reflector Antenna Design and Analysis

Dr. Peter Meincke

Sunday, July 19, 08:00 - 17:00

Abstract:

The course gives an introduction to the design and analysis of single and dual reflector antennas, center-fed as well as offset. After a review of the analysis methods commonly employed for space- and Earth-station reflector antennas, the basic design principles are presented. First, single and dual spot-beam antennas are considered with the relation between size, feed illumination, directivity, and sidelobe level. Second, the influence of blockage by struts, subreflector, and feed is discussed. Third, the origin of cross polarization in offset designs is addressed and it is shown how to improve the polarization characteristics in dual reflector systems by employing the Mizuguchi compensation principle. Hands-on experience in reflector antenna design is obtained during the course by using the software package GRASP (participants must bring their own laptop).

Biography:

Peter Meincke received the M.Sc. and Ph.D. degrees in electrical engineering from the Technical University of Denmark (DTU), Lyngby, Denmark, in 1993 and 1996, respectively. In spring and summer of 1995, he was a Visiting Research Scientist at the Electromagnetics Directorate of Rome Laboratory, Hanscom Air Force Base, MA. In 1997, he was with a Danish cellular phone company, working on theoretical aspects of radio-wave propagation. In spring and summer of 1998, he was visiting the Center for Electromagnetics Research, Northeastern University, Boston, MA, while holding a Postdoctoral position from DTU. In 1999, he became a staff member of the Department of Electromagnetic Systems, DTU. He was an Associate Professor with ├śrsted-DTU, Electromagnetic Systems, DTU, where his teaching and research interests included electromagnetic theory, inverse problems, high-frequency and time-domain scattering, antenna theory, and microwave imaging. Since 2008, he has been with TICRA, Copenhagen, Denmark, where he is currently developing software for reflector antenna analysis. Dr. Meincke won the first prize award in the 1996 IEEE Antennas and Propagation Society Student Paper Contest in Baltimore, MD, for his paper on uniform physical theory of diffraction equivalent edge currents and received the R.W.P. King Paper Award in 2000 for his paper ''Time-domain version of the physical theory of diffraction'' published in IEEE Transactions on Antennas and Propagation, February, 1999.
