摘要： The invention provides a magnetic inductive sensing device (30) comprising a loop antenna (10) for inductively coupling with electromagnetic (EM) signals emitted from a medium in response to stimulation of the medium with electromagnetic excitation signals. The device includes an electromagnetic shield (36) element which is arranged such as to intercept electromagnetic signals travelling to or from the antenna. The shield element is formed of conductive material such as to block electrical field components of incident signals but further incorporates a non-conductive gap in the material so as to prevent the formation of eddy currents. A loop of the antenna is broken by an opening, the opening being bridged by a capacitor, and the device comprises a signal processing means which is electrically coupled to the antenna via only a single point of the antenna, located to one side of the opening.

摘要： An inductive sensing device (22) is for sensing at two different frequencies. The device includes an antenna (24) which comprises at least two loop parts (30, 32), each loop part coupled to a different respective tuning capacitor (36a, 36b) to thereby provide different respective resonant frequencies for the first and second loop parts. The two loop parts are jointly connected to a shared input connection (38) for receiving driving signals for driving both antenna parts. A control means (44) controls a drive circuit (34) to supply the antenna, via the shared input connection, drive signals of each of the frequencies, implementing switching between the two.

摘要： The invention provides a magnetic inductive sensing system for sensing electromagnetic signals emitted from a body in response to electromagnetic excitation signals applied to the body. The electromagnetic signals are generated and sensed by the same loop resonator which comprises a single-turn loop antenna and a tuning capacitor. The loop antenna of the resonator and a signal generation means for exciting the resonator to generate excitation signals are together configured so as to optimize the value of a ratio between the radial frequency of the generated electromagnetic excitation signals and a reference frequency of the antenna, where the reference frequency is the frequency for which one wavelength of the generated excitation signals (waves) matches the circumferential length of the antenna. This ratio, which corresponds to a normalized radial frequency of the generated excitation signals, is maintained between a value of 0.025 and 0.50.
