Compact CPW-fed dual folded-strip monopole antenna for 5.8-GHz RFID application

A coplanar waveguide (CPW)-fed monopole antenna with dual folded strips for the radio frequency identification (RFID) application is presented. The proposed antenna has a very compact size, with, including ground plane, only 14 × 8 mm2, and can operate at the 5.8-GHz band with measured impedance bandwidth and average antenna gain of 450 MHz and ≥5.5 dBi, respectively, and also monopolelike radiation patterns. © 2006 Wiley Periodicals, Inc.
