- Abstract
- In this paper, we propose a dual wide band chip internal antenna which can be applied to actual portable phones. The size of this antenna is 8×3.2×20(mm3). The minimization of this antenna was realized by using meander line structure and spiral line structure on FR-4 of dielectric permittivity εr= 4.4. We can get the wide-bandwidth in the upper band by overlapping high order resonances. The operation frequency of the proposed antenna includes the EGSM/GPS/DCS/USPCS/WCDMA bands for mobile communication systems. The measured bandwidth is HOMHz (940 - 1050 MHz) in the low frequency range and 710MHz (1740 - 2450 MHz) in the high frequency range. The proposed antenna is SMD type to be easily installed in the practical mobile handset. Also we use PCB technology which can allow mass production of low-cost. The antenna has been designed with HFSS of Ansoft company.
