本論文針對應用在行動電話與無線區網路中的天線提出創新的設計。在行動電話天線的設計上，首先提出利用負載一晶片電感於倒F形平板天線上，使得天線具有雙頻操作的能力。而為了降低生產成本，提出可操作在GSM/DCS頻帶的倒F形平板天線，此設計無須晶片電感負載。另外，提出一單極天線與倒F形平板天線結合式天線，該天線可應用在GSM/DCS/PCS三頻段手機上。在無線區域網路使用的天線方面，分別利用倒F形平板天線與整合式單極天線設計出可以操作在2.4/5.8 GHz與2.4/5.2 GHz的新式天線。最後，提出一種結構簡單、製作容易、成本低廉且可應用在無線區域網路中的金屬板天線。

This paper proposes novel antenna designs for cellular phones and WLAN (Wireless LAN) applications. For cellular phones, a dual- frequency PIFA (Planar Inverted-F Antenna) loaded with a chip inductor is constructed. In order to decrease the construction cost, PIFAs without a loading chip inductor for GMS/DCS phones are devised. Besides, a PIFA-monopole antenna for GSM/DCS/PCS is also proposed. For WLAN application, a dual-band PIFA for 2.4/5.8 GHz and a dual-band integrated monopole antenna for 2.4/5.2 GHz are shown. Finally, a novel metal-plate WLAN antenna, having a simple structure and being easy to construct with low cost, is presented.
