| Summary: | 碩士 === 國立臺北科技大學 === 電資碩士在職專班研究所 === 103 === This paper presents an innovative antenna structure which is support most of the GSM/WCDMA/UMTS band. And it can be implemented to the current mobile devices for the multi-band LTE (Long Term Evolution) technology systems. This design features devices to cover LTE(704 MHz~746MHz)、LTE (824 MHz ~ 894 MHz), LTE (880 MHz ~ 960 MHz) and high-band LTE (1710 MHz ~ 2170 MHz) by this single structure to cover the majority of today&;#39;s LTE operating bands. The characteristics of this simple structure can be implemented directly to the printed
circuit board, and achieved the extensive application, while keeping the advantage of saving costs.
This multi-band antenna employs two meandered coupling structure between fed and slot structure to excite three resonance modes, enabling this antenna to achieve the multiple communication bands. The presented bending structure is able
to add a slot to achieve the desired high frequency range in LTE (1710 MHz ~ 2170 MHz) bands. The verification will be executed through the simulation and actual production measurement. The operational frequency of this antenna is: 310 MHz in the low band (700 MHz -1010 MHz) and 650MHz in the high band (1550 MHz -2200 MHz). The area of the antenna radiator is 22.5 × 70 mm2.
