| titleOfInvention | A kind of reading distance RFID label antenna far away being easy to impedance matching |
| abstract | The utility model discloses a kind of RFID label antenna being easy to impedance matching, comprise FR4 substrate, copper paster and label chip; Described FR4 substrate is rectangle, and its upper print has copper paster; Left semicircle groove and right semi-circle groove is had in the bilateral symmetry of the axis of copper paster; Be communicated with by a stria between left semicircle groove and right semi-circle groove, the metal tape between left semicircle groove and right semi-circle groove is divided into isometric upper metal tape and lower metal tape by this stria; Upper metal tape is communicated with by label chip with lower metal tape; A C type groove is had, thin two hem widths in the middle of described C type groove in the below of left semicircle groove and right semi-circle groove; The utility model antenna has wider impedance bandwidth, and 6dB return loss can cover US bands completely; Antenna has bidirectional radiation directional diagram and very low cross polarization; Reading distance is far away, and the maximum reading distance of calculating can reach more than 14.5m, and in whole US bands, maximum reading distance is also all at more than 12m. |
