TRIPLE-BAND MEANDER LINE ANTENNA FOR GSM, DCS AND UTMS APPLICATIONS

A compact triple-band meander line antenna for global system for mobile communication (GSM), distributed control system (DCS) and universal mobile telecommunications system (UMTS) applications operating at the frequencies band of 0.9 GHz, 1.8 GHz and 2.1 GHz is designed. Most demanded wireless communication bands are covered in this design for consumer electronics. The resonant frequencies are 0.9 GHz with the return loss of -21.262 dB and the corresponding radiation pattern with maximum gain of 2.09 dBi, 1.8 GHz with the return loss of -19.011 dB and the corresponding radiation pattern with maximum gain of 2.32 dBi, and 2.1 GHz with the return loss of -20.203 dB and the corresponding radiation pattern with maximum gain of 3.7 dBi. The antenna was printed on a FR4 substrate with dielectric constant of 4.7. The simulated result was verified through measurement in which a good agreement between the simulated and measured result was documented. An application example is shown for the proposed design which is an integrated system to detect the level of electromagnetic field radiation at GSM frequencies.
