Summary:
A novel internal meandered loop antenna for application in a mobile phone for multiband operation is presented. Along the symmetric metal-strip loop structure of the antenna, there are meandered sections for adjusting the antenna’s resonant frequencies. The antenna’s first and second resonant modes (half- and one-wavelength modes) are excited for GSM/DCS operation. With the meandered sections in the loop structure, the antenna’s third resonant mode (1.5-wavelength mode) can be adjusted to be close to the second resonant mode to achieve a wider upper band for DCS/PCS operation. In addition, the central unoccupied region of the proposed loop antenna is used to accommodate the lens of a digital camera. Furthermore, effects of the user’s hand holding the mobile phone with the proposed loop antenna are analyzed in this study.
