Small Antenna and Array Synthesis on Installed Platforms

执行摘要主要目标是在通信、雷达和监视应用的已安装平台上开发具有增强性能的小型天线和阵列。当前和未来的无线系统对更紧凑、更轻、更低成本的天线的需求越来越大。为了满足这些需求，需要新的综合方法和技术来提高天线的性能，这可能会对系统的灵敏度、带宽、空间覆盖、干扰抑制和定向精度产生巨大影响。现有平台上的紧凑型天线往往在电气上很小；这在较低的频率下更加明显，因为天线大小可能是波长的一小部分。目前的紧凑型天线表现出性能限制，这可以通过这个提议来解决。

Executive SummaryThe main objective is to develop small antennas and arrays with enhanced performance on installed platforms for communication, radar and surveillance applications. There is increasing demand for more compact, lightweight and lower cost antennas for current and future wireless systems. To meet these demands, novel synthesis methods and techniques are required to improve antenna performance with potentially great impact on system sensitivity, bandwidth, spatial coverage, interference mitigation and directional accuracy. Compact antennas on existing platforms tend to be electrically small; this is more pronounced at lower frequencies where antenna size could be a fraction of the wavelengths. Current compact antennas exhibit performance limitations which could be addressed with this proposal.
