From October 2006 to March 2007, 31 shoulders (13 men and 18 women with average age of 54.3) with subacromial impingement syndrome, from our department, were selected to form the patient group, An age and gender-matched of 40 asymptomatic shoulders (18 men and 22 women with average age of 52.8) formed the control group. The acromion index was measured on the Grashey view. The distance from the glenoid plane to the lateral border of the acromion was divided by the distance from the glenoid plane to the lateral aspect of the humeral head to calculate the acromion index.

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。
