隨著個人化通訊服務的多樣化與多媒體影音的交流增加，如何設計出合適的天線搭配無線傳輸以及定位辨識功能為本論文所探討的重點。 在天線方面，將以FR4基板為天線本體設計出具指向特性之平板天線，利用NXN天線架構增加可收發角度與範圍，同時考慮垂直與水平之線性極化特性，設計兩種不同極化方向之指向性天線，減少極化上的損耗，天線本體S11數值將低於期望的-10dB以下，效率60%以上，並利用波束成型(Beamforming)技術與反射板，改變波束方向與波束寬度，提高座標點與定位點之間辨識度, 及利用正交分頻多工（Orthogonal frequency-division multiplexing, OFDM）具備高速率資料傳輸的能力與多輸入多輸出（Multi-input Multi-output MIMO）的系統結合在長度70公尺寬度40公尺建築物內達到高速多點資料傳輸與定位辨識。 The diversity of personalized communication services has increased with the exchange of multimedia, How to design an antenna with wireless transmission and Positioning identification function is the focus of the research. We will use FR4 substrate for the directional antenna design, and use NXN antenna architecture to increase the transceiver angle and range, consider the vertical and horizontal linear polarization characteristics with NXN antenna architecture And use beamforming technology to change the beam direction improve the identification between the coordinates and positioning points, and enhance the wireless transmission of data, the transmission will be used OFDM and MIMO technology, S11 of the patch antenna will be less than -10dB below.
