Patent DE-4116232-A1 (DE)
Inventor: SCHENKYR DIETER DIPL PHYS
IPC: H01Q21/24
Filed: 1991-05-17
Abstract: In order to obtain the best possible signal reception in at least two frequency bands with differently polarised wave fields, a first aerial has two individual probes (1, 2) for receiving signals in a first frequency band which couple to the displacement current of the same substantially resonant circuit occurring on a conductive formation (6).
