A series of theoretical and experimental studies on the microstrip patch antennas with dielectric superstrates is carried out systematically. Firstly, a comprehensive survey of the microstrip antenna technology and its theories are presented. Then, two analysis techniques, named as the spectral domain Green's function method and the spectral domain integral equation method are developed. The SDGF method is a simplified analysis technique, which takes advantage of the spectral domain immittance approach to find the dyadic Green's function for the stratified media, and obtains the complete closed-form formulas for radiation patterns, directivity, efficiency, gain etc. Some interesting calculated results are presented. The SDIE method is capable of determining resonant frequency, radiation characteristics, input impedance etc, for the covered microstrip patch antennas. Comparing with other full-wave analyses it reduced computation and mathematical labour remarkably. The singularities near the pole location of the surface-wave modes and the difficulty of the integral computation over infinite range of oscillating integrands are dealt with actively and documented well. Results predicted by the SDIE method agree extremely well with our experimental results for resonant frequencies of various superstrates. The superstrate effects on impedance and radiation characteristics also have been investigated experimentally so that the gap due to lack of measured data and computed results for multi-layered superstrate has been filled to some degrees and two useful observations have been achieved for weakening the resonant frequency shift and optimizing the microstrip antenna gain. As a meaningful application, the design and analysis of a 4×4 patch array are introduced.

实用微带天线普遍加介质覆盖层来防护热，物理损伤和环境影响，也可能在飞行或严酷气候条件下自然形成覆盖层本论文对带介质覆盖层的微带贴片天线系统地作了一系列理论和实验研究首先，对微带天线技术和理论作了全面的综述然后，发展了两种分析方法，称为谱域格林函数法和谱域积分方程法SDGF法是一种简化的分析技术，它利用谱域导抗法来求得分层媒质的并矢格林函数，并得出方向图、方向性系数、增益等参数的完整的闭式公式，给出了一些令人感兴趣的计算结果SDIE法能确定介质覆盖微带天线的谐振频率、辐射特性和输入阻抗等与其它全波分析方法相比，它明显减小了计算量和数学工作量已有效地处理了表面波模极点附近的奇异性和对振荡的被积函数的无限区间积分计算的困难对于不同覆盖层情况下的谐振频率，由SDIE法所预示的结果与我们的实验结果吻合得很好对于覆盖层对阻抗和辐射特性的影响也已作了实验研究这在某种程度上填补了缺少实验数据和计算结果之间的间隙，并得出了缓解谐振频率偏移和优化天线增益的两点有用的结论作为有意义的应用，介绍了一个4×4元矩形贴片天线阵的设计和分析。

Prime Minister Ingraham to attend the ground-breaking ceremony and made a speech, saying the airport in Nassau, Bahamas to the history of the expansion project is the largest public works projects, is the 20th century, successive Bahamas since the 80's would like to complete the objectives of the Government, successive governments have been to ensure that economic development and the new airport facilities in line with the culture and climate, as well as the Bahamas, construction continued at an effective balance between the protection of the environment to choose.

英格拉哈姆总理出席破土动工仪式并发表讲话，称拿骚机场改扩建工程是巴哈马历史上最大的公共工程项目，是20世纪80年代以来历届巴哈马政府想要完成的目标，历届政府一直在确保经济发展与新机场设施能符合巴哈马文化和气候以及工程建设在有效持续保护环境之间进行平衡选择。

Although China is anancient country, you are also confident in the future, is committed to next generation can dobetter than this generation, in addition to your growing economy, we are in line with China inscience and research with regard to the power input , including the construction of infrastructureand the use of technology, China is the world's largest country in the use of Internet technology,that is, we are very pleased that the Internet is today part of the activities, the country also hasthe largest mobile telephone network, for new investment to maintain continued growth, andresponding to climate change, there is new investment, I also hope that China would strengthencooperation in this area.

虽然中国是一个古老的国家，你们也是充满信心展望未来，致力于下一代能够比这一代做的更好，除了你们不断增长的经济之外，我们很配合中国在科学和研究方面所投入的力量，包括建设的基础设施和使用的技术，中国是世界上使用互联网技术最多的国家，这就是我们很高兴互联网是今天活动的一部分，这个国家也拥有最大的机动电话网络，对新的投资保持继续增长，和应对气候变化方面有新的投资，我也希望两国加强这方面的合作。

A recent survey of big investors in Europe by Jefferies, an investment bank, has found that they, too, believe sustained national support for clean-tech industries matters more than an international deal on climate.

欧洲投资银行杰弗里斯最近对大型投资者进行的调查发现，他们也认为国家对清洁科技产业保持支持的情况比气候峰会上的国际协议要好。
