| 摘要 |
The invention concerns a loop-type electronic antenna (2) for identifying radio frequency in a detecting volume (V), comprising at least two conductor wire portions (3) and at least one interconnection box (4) arranged between the wire portions (3), including at least one variable capacitance capacitor. Each box comprises means for controlling the value of the capacitance of the capacitor. The antenna further comprises: means (5) for allocating to each interconnection box (4) a capacitance value for the capacitor communicating with the means controlling the value of the capacitance of the capacitor, and a reader (12), associated with the allocating means (5), comprising analyzing means (33) which determine, by varying the capacitance values of at least one capacitor, said values for which a given quality of detected signals, from in particular at least one radio frequency label located in the detection volume (V), is obtained. |
