fold band-
The radiation pattern of the antenna is more rotationally symmetric, and a more reduction on the sidelobe levels of the antenna is achieved as compared to the antenna with the corrugated soft surface. in conclusion, in the present thesis both theoretical and experimental research works have been carried out intensively on patch antennas based on photonic - bandgap structures. it is shown that our photonic bandgap structures can greatly improve the performance of the patch antennas
該平面圓環結構軟表面天線是在空氣介質的皺褶圓環結構軟表面天線的基礎上改進得到，為了便於比較，我們首先研究了空氣介質的皺褶圓環結構軟表面天線，用fdtd方法並結合pml吸收邊界條件對該天線的性能進行了研究，結果表明天線的帶寬增加，天線的軸對稱性得到了很大改善， e面和h面方向圖的波束幾乎重合，天線的旁瓣和背瓣受到很大的抑制。The western hubei - eastern sichuan area is located at the junction belt between the eastern sichuan folded belt in the sichuan basin and xianexi folded belt, belong to eastern extended part, which is similar to the eastern - sichuan structure in many aspects. for example, they share a structural unit, resulting in the same sedimentary history and the same generation - reservoir - seal assembly as each other
