技術說明

本發明為一種新型微波電路之設計，此微波電路稱為三頻雙工環路器，它亦基於後設材料之電磁帶隙(electromagnetic band-gap, EBG)性質所建構出。首先，將傳統單層蕈狀結構結合懸置微帶線之理論，推廣至多層結構，使其擁有多頻EBG特性，達到電路縮小化效果。接著將三組所設計的雙頻EBG電路作環形串聯，並經過妥善的阻抗匹配，進而完成三頻雙工環路器之設計，它結合了雙工器與環路器之功能，其可使GSM 1800MHz、WiFi 2.45GHz和WiMAX 3.5GHz系統之間，作多頻段與多通道的資料整合。 In this invention, A novel three-port microwave circuit called triplex bi-directional circulator is designed. It is accomplished on the basis of the electromagnetic band-gap (EBG) characteristic of the meta-materials. Firstly, we extend the concept of the traditional single-layered mushroom structure with the suspending microstrip line to the multi-layered structure. In this way, the multi-layered structure can reveal multi-band EBG characteristic and achieve miniaturization. Moreover, we use three sets of proposed dual-band EBG circuit to be series-connected in a ring-type structure. By using proper impedance matching, the design of the triplex bi-directional circulator is completed. It combines the capabilities of the diplexer, the duplexer and the circulator. The triplex bi-directional circulator can integrate three kinds of communication systems with each other, which operate at frequencies including GSM 1800MHz, WiFi 2.45GHz, and WiMAX 3.5GHz, respectively.
