Controlling Radiation Pattern of Spherical Antenna

2006 16th International Crimean Microwave and Telecommunication Technology, 2006
Presented in this paper are the results of theoretical and experimental research of irradiation shift influence on radiation pattern. Scanning limits of antenna beam are determined. Some recommendations for scanning spherical antennas design are given.

Recording of dynamic antenna radiation patterns

IEEE Transactions on Antennas and Propagation, 1973
A concept is presented for recording antenna radiation patterns as functions of two parameters simultaneously. An implementation of the technique results in a significant savings in the measurement time required to document antenna performance as a function of the particular pair of parameters of interest.

Variable radiation pattern of helix antennas

IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003
Two-wire or four-wire helical antennas, which are rod-shaped and space-saving and hence simple in structure, have been attracting attention as antennas to be used for mobile satellite communication base stations. Kawakami et al. (1997) reported that changing the phase shift and the number of turns of wire in the central portion enables vertical pattern

SAMS: antenna radiation pattern acquisition

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
SAMS is a product family in the area of antenna radiation pattern acquisition and processing. It has been developed and is commercialised since 1998, by SILICOM, in partnership with the CNES (French Spatial Agency). The CNES expertise in antenna measurements together with SILICOM's proficiency in software development and in hyper-frequency studies led ...
