The results revealed that screwdrivers with triangle shaped handle could help subjects produce the maximum torque. Besides, using screwdrivers with hexagon shaped handle spent the least time, generated the minimum biceps muscle activity, and bad the least subjective fatigue rating. Moreover, wearing an anti-static glove or being barehanded can produced the maximum torque and spent the least time as well. Experiment 2 evaluates the handle diameter of screwdriver (30 mm, 34 mm or 38 mm) and operation plan. The results showed that the torque increased with the increase of the radius, the operation time and the brachioradialis muscle activity also increased with the increase of the radius.

本 研究共分为三次实验，实验一分析握把造型(八角形、锐角六角形、圆角六角形、枪型、圆角三角形)与手套(棉质手套、防静电手套、赤手)的影响，结果显示三角形造型握把可产生最大扭力，六角形造型握把的锁附螺丝时间最短、二头肌肌肉活动度最低、主观整体疲劳评比最低，防静电手套与赤手状态的扭力最大并且锁附螺丝时间最短；实验二比较握把直径(30 mm、34 mm、38 mm)与作业面的影响，结果显示直径越大扭力越大，但直径越小锁附螺丝时间则越短，且肱桡肌肌肉活动度越低。

These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

在第二章中，我们使用单极天线设计概念，使用双路径架构并於末端耦合来对天线阻抗做匹配，产生涵盖GSM900/DCS/PCS/UMTS四频操作频带，并提高与接地面的辐射高度，以避免电容效应，使天线具有良好的辐射特性；在第三章中，使用倒F形天线设计概念，使用双路径架构於末端耦合，并於辐射臂上采取适当接地点电感效应作输入阻抗匹配，达成涵盖GSM900/DCS/PCS/UMTS系统的四个操作频带；在第四章中，采用倒F形架构并使用耦合馈入方式，使得长辐射金属臂在低频900 MHz附近产生共振，产生低频基频模态及高阶模态，以达成宽频及频宽涵盖GSM900/DCS/PCS/UMTS频带操作，并有效缩减使用体积；最后，分别比较此三种架构的优缺点，再加以业界角度来思考，研发产品天线的流程及思考方向，以及天线应用於可携式导航装置中未来的展望作为本论文的总结。
