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。

In order to describe in detail the structure of mesoscale atmosphere circulation and its evolution, symmetry theory are extensively used in the past fifty years. A large number of wind tunnel and water tank experiments are practiced to reshow the physical process that often appear in the atmosphere and, to some extent, successfully explain many atmsophere circulation characters in surface layer. But because of the planetary reflection and small Re number deformation, these physical experiments can' t represent real conditions of the atmosphere, they also can' t distinct viscous boundary layer separation and non-viscous dynamical separation as well as show the circulation response to surface diurnal heating.
为了详细描述复杂地形区域大气中尺度环流的结构和特征,过去50年来人们广泛采用相似理论,利用风洞和水槽实验再现大气中的物理过程,并在一定程度上成功地给出了大气近地层的一些环流特征,然而由于边界层反射和小Re数形变作用的影响,物理实验的结果并不能真实地再现大气中的实际状况,尤其是不能正确区别边界粘性分离流场和大气非粘性动力分离气流,环流场对地形下垫面日周期热强迫的响应过程也难以再现。
