由於行動通訊技術的提昇快速，使得攜帶電子產品的利 及，例如手機、筆記型電腦等。這些攜帶電子產品為符合便 要求下，一直趨向於小型化的發展，使得内部收容元件的空 小。為順應此一方向，天線目前多已經使用平板式天線。 傳統的此類平板式天線製造時，如第一圖所示，先將金屬材質（例 如銅）的天線1予以沖壓成型，然後再貼合於一塑膠板2上，以構成 一天線組件。由於金屬材質的天線2是以沖壓製造，由於精度不夠， 不能製造小尺寸的天線，使得傳統天線組件必需佔據攜帶電子產品一 定的空間。The rapid advancement of mobile communication technology has made it possible to carry electronic products such as mobile phones and notebook computers. These portable electronic products have been trending toward miniaturization in order to meet the requirements of the requirements, so that the internal housing components are small. In order to comply with this direction, antennas have mostly used flat antennas. In the conventional manufacture of such a planar antenna, as shown in the first figure, an antenna 1 of a metal material (e.g., copper) is stamped and then attached to a plastic plate 2 to constitute an antenna assembly. Since the metal antenna 2 is manufactured by stamping, since the precision is insufficient, it is impossible to manufacture a small-sized antenna, so that the conventional antenna component must occupy a certain space for carrying the electronic product.
進者，由於金屬材質的天線1以沖壓成型，使得天線形狀被限製 成平板狀’才能貼合於塑膠板2上，無法在非為平面的塑膠板上貼合， 此為傳統天線組件製造上的另一瓶頸，有待改善。 在專利合作條例（Patent Cooperation Treaty，PCT)國際公開 日為2005年12月22日國際申請案號為PCT/IL2005/000611之「利用 濕¥體成型之二維天線及其製造方法（Three Dimensional Antennas Formed Using Wet Conductive Materials and Methods for Production thereof)」前案中，其天線製造方法是提供一具至少有一三維表面的 5 200836403 基材，並運用導體塗佈於該至少一二 妥H & 一、准表面，猎此至少在一表面形成 天線包含以導體塗佈而運用於—具有三維表面之基材上。 刖、H體塗佈（a)nduetive GQating)技術來製 體線’但由於寬_及緊實化的絲，使得天叙圖案日舰 雜’如以單純的導塗佈技術4無法達成需求之天線圖案的。 【發明内容】In addition, since the metal antenna 1 is formed by stamping, the shape of the antenna is limited to a flat shape, so that it can be attached to the plastic plate 2, and cannot be attached to a non-planar plastic plate. This is a conventional antenna assembly. Another bottleneck on the subject needs to be improved.
