Abstract :
Presented is an antenna that allows independent and versatile dual frequency and bandwidth reconfiguration by using simple external matching circuits. Simulations suggest that the antenna has a total tuning range of 2118 MHz (from 778 to 2896 MHz) while maintaining a return loss above 6 dB. In addition, the antenna is capable of operating as a penta-band cellular phone antenna. This kind of antenna is typically required to work within the GSM900, GPS1575, GSM1800, PCS1900 and UMTS2100 bands.
