A Compact Printed Monopole Antenna for Dual-band RFID and WLAN Applications
MetadataShow full item record
Design of a simple and compact microstrip-fed printed monopole antenna (PMA) for applications in wireless local area network (WLAN) and radio frequency identification (RFID) is presented. The dual-band operation is achieved from the 9-shaped folded antenna which is printed on a non-conductor backed dielectric. Measured percentage impedance bandwidth of the PMA at the center frequencies of 2.43 GHz and 5.24 GHz are 33.13 (2.14 GHz to 2.99 GHz) and 36.43 (4.40 GHz to 6.36 GHz) respectively. Consistent omnidirectional radiation patterns have been observed in both the frequency bands from the experimental results. The proposed antenna is simple in design and compact in size. It exhibits broadband impedance matching, consistent omnidirectional radiation patterns and appropriate gain characteristics (>2.5 dBi) in the RFID and WLAN frequency regions.
