Abstract :
A monopole antenna integrated with various coplanar waveguide (CPW)-fed meander resonators is presented. A CPW-fed meander resonator combined with a folded one is integrated into a single monopole to produce a multiband antenna in the applications of global system for mobile communication (GSM), global positioning system, personal communication systems and wireless code division multiple access (WCDMA) services. The antenna has exhibited impedance bandwidths from 50 MHz at GSM to 370 MHz at WCDMA less than 10 dB of S11. The antenna gains are -5.8, -3.8, -0.6-dBi at 880, 1570, 2100-MHz, respectively.
