博士 === 國立中山大學 === 電機工程學系研究所 === 98 === In this dissertation, a series of printed multiband antennas for slim mobile communication devices are presented. The study mainly focuses on how to effectively enhance the impedance bandwidth. With the equivalent LC matching circuit integrated in the antennas, wide impedance bandwidth can be obtained without increasing the size of the antennas. Note that the equivalent matching circuit can be formed by the coupling strip and the shorting strip to generate capacitance and inductance, respectively. In addition, the effects on the user''s hand, head and whole body will be analyized. Also, the issue of the hearing aid compatibility will be discussed in this dissertation.
