本研究之主旨，乃首次將超穎物質零階共振器自振式主動天線晶片化，以台積電CMOS 0.18 μm 1P6M製程實現主動天線之主動電路部分，並以矽基板整合被動元件製程實現天線本體，該設計將大幅縮小天線體積。
本論文共提出兩款設計。首款零階共振器自振式主動天線，乃以零階共振器為天線輻射體，並利用交錯耦合對中，兩顆電晶體之閘、汲極間零相位之特性，滿足起振條件，使主動天線於共振器零階模態產生振盪，並將主動電路部分以台積電CMOS 0.18 μm 1P6M製程實現，大幅縮小主動電路體積，成功實現零階共振器自振式主動天線。
其次，為實現零階共振器自振式主動天線晶片化，乃以前一款設計為基礎，以矽基板整合被動元件製程取代印刷電路板實現另一款零階共振器，並利用國家晶片系統設計中心(National Chip Implementation Center, CIC) 提供之覆晶技術(Flip chip)將主動電路晶片及天線輻射體晶片以Bumper連接，實現首款晶片化之零階共振器自振式主動天線，其微小體積使在使用中不會浪費過多空間，充滿彈性及機動性，目前晶片已在下線階段，待日後晶片製作完成便會進行量測。

This study focuses on the novel on-chip metamaterial-based self-oscillating active integrated antenna (AIA) using zeroth-order resonator. The active circuit of AIA is performed by using 0.18-μm CMOS technology. Moreover, the antenna part is performed by using the integrated passive device (IPD) process.
Two designs are researched and developed in this thesis. First of all, a novel self-oscillating AIA based on zeroth-order resonators is proposed. The connecting line between the gate and the other drain terminals in a cross-coupled pair is broken up to insert a zeroth-order resonator in between. By utilizing the zero-phase-shift property of a zeroth-order resonator, the phase of the feedback loop is zero and the oscillation happens. The oscillation parameters are investigated in details. The size of active circuit is drastically reduced by using 0.18-μm CMOS technology.
Secondly, to achieve on-chip metamaterial-based self-oscillating active integrated antenna (AIA), the circuit layout of the previous case is re-investigated to develop another zeroth-order resonator. Different from the former design, in the latter case, the antenna part is performed by using integrated passive device (IPD) instead of PCB process. The first on-chip design of metamaterial-based self-oscillating AIA is by using flip chip technique of National Chip Implementation Center (CIC) to combine the integrated passive device (IPD) process with 0.18-μm CMOS process. The small size makes it full of flexibility and mobility. The chip is in the tape-out stage now, and it will be measured after it is totally completed in the future.
