本論文提出一新式週期性覆背式有限寬度共面波導電磁帶隙結構,並對其週期性電磁帶隙結構進行理論研究與其量測數據之探討。此外,我們也提出了在準靜態的假設之下,不連續結構的等效集總電路模型,此電路模型可以很容易的放入電腦輔助軟體中模擬,使得對週期性結構特性的預測更為準確。由全波模擬、等效電路模型、及量測數據的結果中,証實了全波模擬及分析公式的可行性。在實際調整電路結構的過程中,我們發現週期性電磁帶隙結構可以達成控制其傳播的特性、帶隙的範圍、慢波因子、伯洛齊阻抗以及洩漏波天線主波束的目標。此外,由模擬結果與實驗量測的一致性也顯示設計程序及分析方法的正確性。

A novel periodic electromagnetic bandgap structure for the finite-width conductor-backed coplanar waveguide (FW-CBCPW) is investigated theoretically and experimentally in this thesis. In addition, the quasi-static equivalent lumped circuit models of the discontinuities formed between two sections are evaluated and incorporated into the CAD simulation to get better prediction for periodic structure characteristics. Good agreement among the results of full-wave simulation, equivalent-circuit model, published data, and measurement supports the usefulness of the proposed full-wave simulation and also validates the analytical formulas. By properly adjusting the circuit configuration, the periodic EBG structure with controllable propagation characteristics, which include the bandgap zone, the slow-wave factor, and the Bloch impedance for guided wave as well as the radiation main beam for leaky wave, may be achieved. In addition, the good agreement between simulation results and experimental data justifies the design procedure and validates the present analysis approach.
