N2 - A novel multiband high dielectric antenna (HDA) using a ceramic puck is proposed for mobile wireless communications terminals. This HDA operates over the five frequency bands, viz. GSM850, GSM900, GSM1800, PCS1900, and WCDMA2100. A ceramic puck with high dielectric constant is placed at the feeding point of the circuit board to increase bandwidth and radiation efficiency. The total volume of the implemented antenna is 40×9×7 mm3. It has a ceramic puck whose size is 6.3×4.5×4.2 mm3. Compared to the antenna without the ceramic puck, the proposed antenna exhibits a significantly wider bandwidth, especially in the low frequency region. The measured average gains for the proposed antenna are 4.73 and 3.35 dBi in the GSM850 and GSM900 bands, respectively, while they are 7.31 and 4.76 dBi for the antenna without the ceramic puck. There is no significant performance variation in the high frequency band caused by the ceramic puck.
