本篇論文提出一種應用於平板通訊裝置之尺寸且結構簡單的MIMO（多輸入多輸出）( 8x8 )天線。其結構是背面地覆蓋共平面波導方式(Coplanar Waveguide with Ground Calculator ) ，以CPWG饋入方式設計倒F型天線(Printed Inverted-F Antenna；PIFA)，利用Antenna Magus 模擬軟體來分析，設計出雙頻段MIMO天線以符合2.4GHz和5GHz (頻帶涵蓋範圍為2400-2500MHz and 5000-6000MHz) 雙頻作為主架構，且在無反射天線實驗室(Chamber)進行量測，分析天線的基本特性如效率量測、反射損失、 增益、 場型，完成實務平板天線之設計與驗證，製作出符合手持式裝置常用的雙頻段天線。;This dissertation proposes a MIMO (Multiple Input Multiple Output) ( 8x8 ) antenna with a simple structure and suitable size for a tablet communication device. Its structure is the Coplanar Waveguide with Ground Calculator, and the Printed Inverted-F Antenna (PIFA) is designed by using the CPWG feed method. Antenna Magus simulation software is used to analyze the dual-band MIMO antennas are based on dual-band 2.4GHz and 5GHz bands (frequency bands covering 2400-2500MHz and 5000-6000MHz) and are measured in a non-reflective antenna chamber to analyze basic antenna characteristics such as efficiency measurements , Return loss, gain, field pattern, the completion of practical design and verification of flat-panel antenna to produce a dual-band antenna commonly used in handheld devices.
