碩士 === 南台科技大學 === 通訊工程研究所 === 99 === In this thesis, two the printed coupled-fed loop antennas for the mobile phone application are proposed, and they also comply with the eight-band operation bandwidth of LTE700/GSM850/900/DCS/PCS/UMTS/LTE2300/2500. By the excited metal strip different positions, the first antennas form dual-mode resonance. This result makes the application of frequency bands achieve good impedance operating bandwidth. Besides, in order to reduce the antenna’s size, the second antenna’s loop route adds chip inductor and the 5 mm high metal patch to reduce area and adjust antenna’s impedance characteristics. Therefore, it satisfied the impedance bandwidth of eight-band. The volume of proposed antenna is 14×50×5 mm3 and it is also used for slim mobile phone applications. Furthermore, the SAR issues which the mobile market demands for presently are simulated and analyzed in this dissertation.
