Tri-Band Reconfigurable Antenna for RFID Applications

Summary form only given. With the tremendous advancement in communication technology followed by ever growing consumer demands, the need for multifunctional wireless communication devices is more than ever felt. In recent years, this has also been the case for RFID applications where different frequency bands are required for different contents of the scanned package and detection range. In particular, studies have been carried out to demonstrate electronic tunability using loading effects of capacitive elements such as PIN diodes or varactor diodes. In this research, we have used a similar approach to design a compact, versatile slot antenna with enhanced tunability operating in three frequency ranges in the UHF band
