To overcome the drawbacks in the weight and cost of the antenna with the corrugated soft surface, a new patch antenna with patch rings is designed. Its weight is about 1/4 less than the antenna with the corrugated soft surface and it is inexpensive. Good experimental results are obtained. 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.
为了克服皱褶软表面天线份量重,加工费用贵等缺点,我们对空气介质的皱褶圆环结构软表面天线进行了改进,将周期分布的皱褶圆环平面化,并保持结构的软表面特性,设计出了一种新的平面圆环结构的软表面天线并进行了实验研究,加工的平面圆环结构天线比皱褶圆环结构天线重量减轻了约1/4,加工费用大大降低,所取得的实验结果显示,该平面圆环结构软表面天线的方向图的轴对称性得到了改善,在俯仰角从0°~-90°的范围内天线H面的波束与E面重合,与皱褶圆环结构相比,天线的旁瓣和背瓣受到了更大的抑制,E面方向图上+120°方向的旁瓣被明显削弱。

On the geometric modeling, flat surface and curved surface are used to mesh and describe the model;on the electromagnetic modeling. Different basis functions( flat surface roof-top basis function, flat surface RWG basis function, curved surface roof-top basis function, curved surface RWG basis function) and different test functions (line-matching, Galerkin method) are applied to different cells(plat rectangle facet, triangular patch, Bezier patch, parametric surface, curved triangular patch etc.).

We present an efficient approach for generating the correspondence between two homeomorphic 3D polyhedral models. The user can select vertices on the polyhedra to decompose the boundary of each polyhedron into the same number of morphing patches. Further, the user can specify the feature points on the morphing patch pairs to improve the morph. After the morphing patch pairs are be mapped to 2D regular polygons, they are merged and reconstructed to generate a morph. In the main procedures of our approach, we propose an easy mapping method and a foldover-free warping technique. And we also propose a most efficient merging algorithm. The merging can be completed in O.
