| Popis: | 103 This paper presents an innovative antenna structure, to enhance the current mobile devices for the multi-band LTE (Long Term Evolution) technology systems and applications. This design features devices to cover LTE (704 MHz ~ 746MHz), LTE (824 MHz ~ 894MHz), LTE (880 MHz ~ 960MHz) and high-band LTE (1710 MHz ~ 2170MHz) via this single structure to cover the majority of today&;#39;s LTE operating bands. The characteristics of this simple structure can be applied directly to the printed circuit board, to achieve 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 excite additional resonant modes to achieve the desired low frequency range in LTE (1710 MHz ~ 2170MHz) bands. This paper will study the gap in each capacitive coupling antenna structure corresponding to the antenna characteristics. The verification will be executed through the simulation and actual production measurement. The operational frequency of this antenna is: 310MHz in the low band (700MHz -1010MHz) and 540MHz in the high band (1710MHz -2250MHz). The area of the antenna radiator is 22.5 × 70 mm2. |
