9. A radio frequency identification (RFID) reader comprises:
-
an antenna operably coupled to receive an inbound radio frequency (RF) signal and to transmit an outbound RF signal;
a radio frequency (RF) front end operably coupled to convert the inbound RF signal into a inbound near baseband signal and to convert an outbound near baseband signal into the outbound RF signal;
a digitizing module operably coupled to convert the inbound near baseband signal into a digital inbound baseband signal;
pre-decoding module operably coupled to convert the digital inbound baseband signal into bi-phase encoded data; and
a decoding module operably coupled to decode the phase encoded data to produce decoded inbound data;
an encoding module operably coupled to encode outbound data to produce encoded outbound data; and
digital to analog converter operably coupled to convert the encoded outbound data into the outbound near baseband signal, wherein the antenna includes;
a substantially planer substrate having a first surface and a second surface; and
a helical winding having a first pattern, a second pattern, and a plurality of interconnections, wherein the first pattern is affixed to the first surface and the second pattern is affixed to the second surface, and wherein connection nodes of the first pattern are coupled to associated connection nodes of the second pattern by the plurality of interconnections. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
