CPC H04B 5/0031 (2013.01) [H01P 1/062 (2013.01)] | 17 Claims |
1. A non-contacting rotary joint for transmission of electrical signals across a non-contacting interface defined between two relatively-movable members, comprising:
a transmitter configured to transmit a signal across a non-contacting interface;
a near-field probe arranged in spaced relation to said transmitter and operatively arranged to receive said signal transmitted across said interface;
said near-field probe having a signal capture area for receiving said signal transmitted across said interface;
said signal capture area comprising a segmented signal receiving strip having a length sized for a desired low frequency signal content of said signal and configured to receive a range of frequency signal content of said signal that includes said desired low frequency signal content of said signal, said segmented signal receiving strip comprising:
a first signal receiving segment having a first frequency response;
a second signal receiving segment having a second frequency response and electrically coupled to said first signal receiving segment;
a third signal receiving segment having a third frequency response and electrically coupled to said first signal receiving segment;
said second frequency response of said second signal receiving segment being less than said first frequency response of said first signal receiving segment; and
said third frequency response of said third signal receiving segment being less than said first frequency response of said first signal receiving segment; and
receiving electronics operatively arranged to receive said range of frequency signal content received by said segmented signal receiving strip via said first signal receiving segment.
