本論文介紹低溫共燒陶瓷(LTCC)繞線多層電感應用的優勢，且提出兩種微型化威爾金森功率分配器設計佈局。此技術的應用與佈局可以大幅縮小空間上的運用，能成為使用高阻抗傳輸線佈局的威爾金森功率分配器替代方案，接著以公式驗證和全波電磁模擬軟體 ( HFSS )在奈米的單位環境下進行模擬，並且使用( Sonnet )、(ADS) 設計等效電路以及各項驗證，在規格2.0mm x 1.2mm x 0.6mm 實現元件設計，使中心頻率為900MHz ，以對稱結構佈局使用隔離電阻劃分兩輸出端埠，達到等功率分配和良好的隔離度。現今，運用低溫共燒陶瓷所製成的多層繞線電感的技術相當成熟，因此種替代方案是可以實行，並預期原本特性效果，透過多層繞線電感可以同時設計電感以及其電容，在確立電感及電容數值後以此設計微型化威爾金森功率分配器。

This dissertation will introduce the advantage of multilayer inductors wound edge by the technique of low temperature cofired ceramic (LTCC), and will propose two design layout of miniaturized Wilkinson power divider. The application of this technology and layout can significantly reduce the use of space, and can become a possible alternative of Wilkinson power divider layout which settled by high-impedance transmission line. Following this, this paper will simulate the experiment in units of nano environment to see whether the formula and full-wave electromagnetic simulation software (HFSS) are correct. In addition, in order to reach the same power allocation and good isolation, the experiment uses symmetrical structure which uses isolating resistor to divide two output port. Also, the experiment uses the technique of (Sonnet) and (ADS) to design Equivalent circuit. All of these are aiming to see the result of the testing. In the meanwhile, the standard of the component design specifications is 2.0mm x 1.2mm x 0.6mm , and the center frequency is expected to achieve 900MHz .Today, the technique of LTCC multi-layer winding inductor is quite mature, and therefore this kind of alternative is highly likely to be implemented. Also, it is expected that the miniaturized Wilkinson power divider can be designed by maintaining its original features under some conditions. In other words, multilayer inductors wound edge can design both of multi-winding inductance and capacitance at the same time, and can ensure the establishment of inductor as well as the capacitance value.
