T-shaped Broadband CPW - fed Folded-Slot Antenna for 5.8 GHz RFID Applications

摘要

A novel design of T-shaped broadband CoPlanar Waveguide (CPW) - fed folded slot monopole antenna is proposed for the application of Radio Frequency Identification (RFID) at 5.8 GHz. The proposed antenna is fabricated on FR-4 substrate and having the size of 16.5 mm x 20 mm. The bandwidth of 30.17% and peak antenna gain of more than 4.15 dBi has been achieved from the proposed antenna through simulation and testing. The fundamental parameters of antenna which meets the acceptable standards are measured. The radiation pattern of broadside and bidirectional in E-Plane and omni directional in H plane are also observed.
