Abstract

A novel design of spiral strip monopole antenna fed by a coplanar waveguide (CPW) for radio frequency identification (RFID) applications is presented. The designed antenna, which, including the FR-4 substrate is, only 16.5 mm in length and 20 mm in width, can operate at the frequency of 5.798 GHz and 4.15 dBi gain, respectively. This antenna is suitable for radio frequency identification applications in the 5.8 GHz band. The fundamental parameters of the antenna such as return loss, VSWR, gain and polarization which meets the acceptable antenna standards are obtained. Simulation tool, based on the method of moments (ZELAND IE3D version 12.0) has been used to analyze and optimize the antenna. These properties with compact and uniplanar structure make the antenna suitable for use as RFID tags.
