摘要

為因應輕薄短小競爭日益激烈的手持式通訊3C 產品，無線射頻將成為重點項目之一，而現況都以產品主體以外方式進行設計及製造，應用於GSM、BT、WIFI、GPS 等無線技術。在產品上有限空間裡為滿足穩定的場型和功率，常因此造成產品上的無線射頻不穩定狀態，或是為求無線射頻穩定而使產品內結構甚至ID 外觀形狀都被迫改變。
本文主要使用微結構射出成型技術應用到的產業類別，及運用於無線射頻天線技術層面上的優勢與缺點，並闡述整個實驗過程中為配合微結構射出成型技術，所衍生配套的相關輔助完成技術，諸如微模具製程及工法、複合材料的種類及應用等。
實驗進行有關GSM 射頻天線為例的改善，文中說明了無線射頻天線沿革，在實驗中主要是針對成型出的原型射頻天線、金字塔(3D)型微結構天線與圓柱(3D)型微結構天線進行驗證，在電波暗室透過現行業界的無線通訊測試儀測試功率3D 場型值，比較出一般無微結構天線場型值區間0.39db~27.90db，提升至含微結構天線11.60db~16.80db，更加穩定的場型區間值，相信本文各項基礎數值完成後不僅後續新產品機種也能夠延用此架構，更可以縮減開發成本及穩定移動手持式產品天線射頻場型的效益。

Cope with short, light increasingly competitive handheld communication 3C products, radio frequency (RF) will become one of the key projects, the status of all manner outside the main body of the product design and manufacturing, wireless technology used in GSM, BT, WIFI, GPS. To meet field and power in the limited space on the products, often resulting unstable state of the radio frequency (RF) products, or for the sake of wireless RF leaving the product within the stable structure even the ID appearance shape are forced to change.
In this paper the use of micro-structure applied to the injection molding technology industry category, the completion of technical and applied on the advantages and disadvantages of the technical aspects of radio frequency antenna, and elaborated throughout the experiment with the micro-structure of injection molding technology, derived from supporting auxiliary, such as micro-mold process engineering methods, composite types and applications.
The experiment the improvement of the GSM RF antenna, for example,described in the text of the wireless RF antenna Evolution, in the experiment was mainly for forming a prototype of the RF antenna, the pyramids (3D) micro structure of the antenna with a cylindrical type micro structure (3D) antenna authentication in the anechoic chamber through the existing industry wireless communication tester power 3D field-type value, general micro-structure of the antenna pattern value range 20.39db to 27.90db upgraded to containing the micro-structure of the antenna 11.60db ~ 16.80db, more stable field interval value, I believe that this article of the basis value not only to complete the follow-up of new product models can continue to use this framework can reduce development costs and stability benefits of mobile handheld antenna RF field type.
