Design of a multiband coupled-meander-line monopole antenna for M2M applications

This work proposed a highly compact multi-bands antenna design based on the coupled meander-line folded monopole for M2M applications. This novel antenna is design to cover GSM / DCS / PCS / PHS (900 / 1800 / 1900 MHz), WCDMA / IMT-2000 (1920-2170 MHz), and Zigbee / Blutooth / WLAN (2450 MHz), and WiMAX / WLAN (5150-5350 MHz) with the physical size of 70 mm × 11.4 mm × 0.8 mm. Good agreement between the measured and simulated results is observe. The excellent measured gain performance at anchonic far-field chamber validates this useful design approach.
