NOVEL COMPACT CPW-FED PRINTED SLOT ANTENNA FOR 5.8-GHz RFID APPLICATION

摘要

A multisleeve slot monopole antenna with coplanar waveguide fed is proposed for radio frequency identification (RFID) tag applications. The designed antenna with the size of 12 × 13 mm~2 including the FR-4 substrate can operate at 5.8 GHz with the gain of 3.45 dBi in the measured bandwidth of 11.38%. Broadside and bidirectional E-plane and almost omnidirectional H-plane radiation patterns are observed. These properties with compact structure make the antenna suitable for 5.8-GHz RFID applications.
