摘要： An antenna 100 for a radio frequency identification (RFID) system is disclosed. The antenna 100 has a radiating element 102 that comprises a first shaped segment 110 and a second shaped segment 118. Each of the first 110 and second 118 shaped segments comprises two lobed portions 112. The radiating element 102 also has a junction 114 from where each of the first 110 and second 118 shaped segments extends. The first shaped segment 110 is spatially displaced from the second shaped segment 118 and is electronically interconnected through the junction 114. Specifically, one of the two lobed portions 112 of the first shaped segment 110 corresponds with one of two lobed portions 112 of the second shaped segment 118 for forming a first loop 120 having a first current flow therethrough for for inducing a first magnetic field 200, and the other two lobed portion 112 of the first shaped segment 110 for forming a second loop 120 having a second current flow theretrough for inducing a second magnetic field 200.

摘要： An antenna for radio frequency identification is disclosed. The antenna comprises a first radiating element having at least one loop element and a second radiating element spatially displaced from the first radiating element and having at least two interconnected loop elements. The antenna further comprises a coupler for electrically coupling the first and second radiating elements. Specifically, when a first current flows in the first radiating element for generating a first magnetic field and a second current flows in the second radiating element for generating a second magnetic field, one of the first and second magnetic fields superimposes the other of the first and second magnetic fields for generating an interrogation region in the near field of the first and second radiating elements.
