CPW-Fed Antenna with Two Rectangle Slots for RFID/Wideband Applications

This paper presents a CPW-fed antenna for RFID/wideband applications. This Antenna satisfies the licensed frequency band of WLAN (5.15-5.85)GHz application and a resonant frequency for RFID at 5.8 GHz for h= 0.5mm having return loss lower than -10 dB. This antenna is designed on a substrate with dielectric constant 4.4. With a size 27.5mmx28mmx0.5mm the antenna operates for wideband application. The effects of shape, length, size, and location of feeding point, substrate and their thickness have been evaluated. And obtained 2D radiation patterns with elevation, VSWR, Return loss, gain and antenna efficiency. The simulation results of this antenna are analyzed by using Method of Moment (MoM) from IE3D software.
