本論文分為兩大主題，第一項主題為超寬頻MIMO天線設計，不同於一般文獻上的超寬頻天線採用大面積的平板天線激發，本論文使用一環圈天線耦合激發短路單極天線的方式得以實現出超寬頻天線，並且運用一般常見的挖槽孔的方式有效的在5.8 GHz附近製造出頻帶截止的效果。接著採用耦合元件的隔離機制應用於無線網路存取點(AP)天線上，在超寬頻的頻帶內隔離度皆大於17.5 dB，天線最大增益達到6 dB，且除了截止頻帶外，其餘輻射效率皆達70%以上。第二項主題為毫米波60 GHz天線設計以及近遠場的特性探討，運用一般廣為人知的八木天線在Silicon-IPD製程上設計出一個指向性天線，其最大增益達到5.65 dB且輻射效率為75%，實做的晶片面積大小為 。最後藉由此晶片天線進行兩天線間近遠場的探討，其中包含了因天線旋轉角度所產生的極化不匹配，透過Friis transmission equation得知增益與S21的關係。為了解決晶片間傳輸線上的訊號損耗，我們提出Mini-LAN的方式在兩個收發機上搭載A-IPDs (Antenna IPDs)作傳輸，在實驗中假設發送端輸出功率為-30 dBm的情況下，在距離7mm的距離內皆可以傳送π/2-BPSK的調變訊號。

This thesis treats two main topics. The first topic is design of a UWB MIMO antenna. Unlike the generally used large area patch antennas, this thesis uses a loop structure to coupling feed the shorted monopole. Applying the commonly used slot technique, a band notch at 5.8 GHz was added. A coupling element was employed to realize the required isolation in an access point (AP) MIMO antenna. In the entire UWB operation frequencies, the isolation was above 17.5 dB, with the best gain of the UWB antenna being 6 dB. Except the band notch frequency, the efficiency reached 70% in UWB frequency. The second topic is design of millimeter wave 60 GHz antenna and investigation of its near and far field characteristic. First, a generally known Yagi antenna designed on a Silicon-IPD. The Yagi antenna has a maximum gain 5.65 dB and efficiency of 75%. The area of antenna chip size was . Finally, we research the near and far field characteristics, including the polarization-mismatch due to different chip antenna orientations. In order to reduce the signal transmission loss in the copper interconnections between chips, over the air mini-LAN communication using two transceiver carrying A-IPDs (Antenna IPDs) was proposed. Near field antenna gain and S21 were employed in Friis transmission equation. Assume the output power of Tx is -30dBm, we can transmit the π/2-BPSK signal within 7 mm.
