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...
This work proposes a highly compact dual-band antenna design based on meander-line folded monopole for GSM/DCS handset applications. The first experimental prototype is design to cover GSM/DCS bands under the physical size constrain of 33 times 4 times 3 mm3. Good agreement between the numerical results and measured data is obtained. The acceptable measured gain performance of the first prototype...
This paper first proposes a cost-effect test-bench design concept in which an embedded antenna array composed of 4 multi-band, dual-polarized antennas is utilized to measure the environment electromagnetic noises. Instead of the un- user-friendly metal-shielding environment or expensive chamber room solutions, the proposed ATE can be used to clarify the root-cause and to improve the low yields issue...
