本論文中將介紹標籤天線的設計原理及高阻抗表面結構的特性，進行薄形化小尺寸高阻抗表面結構的研究與設計。製作上採用印刷電路板，降低製作成本以更具競爭力。預期將標籤天線放置於導通之平行金屬板間。
為了改善其中兩面平行金屬板對於標籤天線的影響，標籤天線將採用槽孔型式的設計；此外，利用電磁帶隙存在高阻抗表面特性，具有降低表面波的生成，將在背面金屬與天線間加入電磁帶隙與背面環境作區隔，以降低背面金屬對天線的影響。
此外，以非平面式槽孔結構設計一可伸入三面金屬環境中的射頻辨識讀卡機天線，而槽孔結構的設計使得槽孔間的電場垂直於上、下兩面金屬導體，根據虛像電流理論可產生建設性干涉的效果，以降低平行金屬板的影響。而且此讀卡機天線亦可解決當標籤天線置於較深入之位置時，使用目前手持式射頻辨識讀卡機讀取標籤天線，可能造成無法正常讀取的問題，以增加可應用的範圍。

In this thesis, the design rule of the tag antenna and the properties of the high impedance surface structure are studied. We proceed to design the low profile and miniature high impedance surface structure. In order to be more competitive, we use PCB plates for fabrication to reduce the cost. The tags are intended to be placed inside two shorted metallic plates.
In order to reduce the effect of the two parallel metallic plates, we use the slots to design the tag antenna. The EBG structure behaves as a high impedance surface and suppresses the surface wave. We add the EBG structure on the back of the antenna to reduce the back metallic effect.
We use slot structure to design the non-planar RFID reader antenna that can be placed inside the three metallic plates to read the data. For the slot structure design, the electric field between the slots is perpendicular to the upper and lower metallic plates. According to the image theory, the induced image current will result in constructive effect to reduce the metallic effect. Finally, the hand-held RFID reader may not identify the RFID tag as the RFID tag placed at position deeper inside. The proposed non-planar reader can solve this problem to be used for more applications.
