本論文主要在探討平板天線，天線實作方法是使用將輻射金屬線直接印刷在基板上的技術，使得天線具有輕薄短小的優點，具容易與電路基板相結合，提昇製作的便利與降低成本的特性。
在本文中利用玻璃基板（FR4），實作平板天線（窄頻）、倒Ｆ型天線（雙頻）和槽孔領結天線（寬頻）。在天線的設計過程中，首先參照書本、論文等文獻為參考，再分別以高頻模擬軟體IE3D和HFSS分別來模擬三支天線。再以FR4板來實現並用網路分析儀來量測其反射係數與用無反射室實驗室來量測天線的場形。

In this thesis, we discuss planar antenna implemented by directly printing conducting metal on the substrate (FR4) to have the advantages of compact size, manufacturing convenience, reduction of cost, and easy combination to other circuits.
The patch antenna (narrow band), inverted F antenna (dual band) and slotted bow-tie antenna (broad band) are fabricated on FR4. First, we referred to books and thesis and simulated three different antennas by using IE3D and HFSS, respectively. Finally we use FR4 to fabricate the antenna and use the vector network analyzer to measure the reflect coefficient、antenna impedance and the antennas pattern in the chamber.
