中文摘要 本篇論文將實現簡單結構的透明單極平板天線,其是由一個挖了一個小方型槽孔的輻射體及一個方形接地面組合而的架構。此原型天線是利用我們自製的基板—使用磁控件鍍機於Polyester透明塑膠薄膜上鍍上一層奈米厚度的Indium Tin Oxide (ITO)的透明導電膜,並在其上刻製我們所要的天線幾何結構。
在天線的設計方面分為兩部分,第一部分說明高頻的頻寬可藉由調整輻射體上的槽孔大小來進行改變,使天線能更隨地意設計成具有DCS、PCS、PHS、UMT、WCDMA、WiBro、802.11a WLAN和UWB等多項應用之雙頻帶天線。第二部份則是僅改變雙頻帶之接地面之大小即可移動高低頻的共振頻率,使雙頻帶天線結合為具有WCDMA、WiBro、DMB、WLAN、WiMax和UWB之超寬頻帶之應用。最後更將此透明天線與一般的銅天線來做比較,發現透明天線的頻寬都會比銅天線來得寬一些,但在場型上並不會相差很多。
這類的天線可以很輕易地達到輕薄短小之外型功能,更因為這透明導電膜之性質,此天線亦能達到反射紅外線及透明無形之特色。也由於這天線外型上的突破,天線的設計就不用為了美觀及方便而冒著會影響效能的風險刻意縮小。
英文摘要 In this paper, we present a novel design for a planar transparent monopole antenna consisting of a rectangular patch with a small notch in it and a ground plane. A prototype of the proposed antenna is fabricated on a polyester plastic, on which ITO film is deposited by magnetic sputter, and make the shape of the antenna we want on the transparent conductor films.
There are two parts in the design of the antenna. The first part is about the bandwidth of the high frequency, which is affected by the size of the notch on the radiation plane. The results show that the proposed transparent dual-band antenna can be applied to DCS、PCS、PHS、UMT、WCDMA、WiBro、802.11a WLAN and UWB. The second one is about the UWB antenna. The resonant frequency of the high and low frequency can move as the size of the ground plane changes. That will make the dual-band antenna the UWB antenna gradually, which can be applied to WCDMA、WiBro、DMB、WLAN、WiMax and UWB. Finally we also compare the ITO antenna with the Cu antenna. We find the ITO antenna is wider than the Cu antenna in bandwidth. But in the radiation pattern, Both of them have the similar pattern .
This kind of antenna can be smaller and lighter. Moreover, it can have the characteristics of flashing back the infrared rays and transparence owing to the quality of transparent conductor films. Due to the breakthrough in appearance, the designer need not minimize the size of the antenna at the risk of affecting its efficiency for convenience and good appearance.
