摘要

科技日新月異，無線通訊產品成為人類越來越方便的溝通工具，對於無線模組以及天線的研發設計，扮演著越來越重要的角色，尤其是輕便短小，價錢便宜的設計，成為設計上的趨勢及要求。但是在縮小化的過程中，相對的帶來天線性能的損失，如何取捨便成為另一個重要的課題。 本篇論文針對藍芽系統的無線耳機天線，以節省材料成本以及增加產品穩定性為考量因素做為設計天線重點考量因素，依據應用曲折型單極天線(HFSS)模擬結果於藍芽頻段2402MHz~2480MHz之天線設計測試，並與不同曲折樣式之天線在不同頻寬進行性能比較。

The science and technology change with each passing day. Wireless communication product is a convenient communication tool for the human. The research and design of wireless module and antenna component play the important role. In particular, smaller and cheaper design turns to be the tendency and request of design. However, the efficiency and gain will decrease the antenna size. The trade off between the antenna size and gain is another important topic. The study focuses on the design of the wireless headset antenna of blue tooth system. The low material cost as well as the high product stability is two important factors to design the antenna of Bluetooth headset. Base on the HFSS simulation results, the meander line monopole antenna is applied for the frequency band 2402MHz~2480MHz of Bluetooth headset to design its antenna. The characteristics of the different meander line monopole antennas as compared under there different frequency bands.
