在本篇論文中，一開始時，我們主要是探討平面天線在無線通訊的一些實際應用及其所面臨的挑戰，之後我們亦針對目前比較廣泛使用的頻帶來作一些天線設計，如ISM頻帶使用微擾技術的圓極化寬槽孔天線及環型金屬片負載的平面單偶極天線設計；3G頻帶的短路堆疊天線設計；結合GSM/GPS雙頻帶之車用型微帶天線設計以及滿足個人行動通訊和區域網路跨系統頻帶的GSM/ISM短路堆疊天線設計；最後我們也提出了結合ISM 5.2及5.8 GHz雙ISM頻帶的低成本高增益堆疊天線設計；在這些天線設計中，我們除了要求其必須滿足各系統的頻寬規定之外，對於天線場型、增益的性能表現，也希望其亦能達到最佳的性能表現的。

In this paper, at the beginning, we focused our studies on the practical planar antenna designs for wireless communication. We also proposed several antenna designs operating at the widely used bands, such as the ISM, GSM, GPS, 3G bands and their combinations. For the antenna designs at these bands, the circularly polarized wide slot antenna and planar monopole antenna with the conducting plate loading for ISM band application, shorted stacked mircostrip antenna for 3G band application, and the low cost high gain 8Í8 stacked patch array for dual ISM band application have been presented. To provide mobile communication and the accurate position of the user as well, the GSM/GPS dual-band antenna suitable for vehicle application is presented. Finally, the GSM/ISM dual-band antenna designed for the personal communication and wireless local area network is also shown. The performance we have achieved in these antenna designs not only satisfy the specific requirements of the system, but also show good antenna pattern, and gain.
