Title:
ISOTROPIC ANTENNA
Document Type and Number:
WIPO Patent Application WO/2004/086559
Kind Code:
A1
Abstract:
An isotropic antenna where the radiation pattern is uniform in all directions. The isotropic antenna comprises a spool (11) of an electric insulator having conductor winding parts around three orthogonal axes. A conductor of nonmagnetic metal is wound, as a core material, around the bottom part at the winding part (12) of the spool in series or parallel. On the outer layer of the core material part, three systems of coil elements (14X, 14Y, 14Z) are formed using an insulated conductor of nonmagnetic metal and the coil elements (14X, 14Y, 14Z) wound independently around three axes are connected in series or parallel for the purpose of reception or transmission.
