摘要 提出了一种多层介质悬置微带线天线结构,以改善天线的频扫特性。分析表明该结构不仅可以确保天线工作在效率较高的天线模工作区,而且它的泄漏常数在相当宽的范围内随频率都能平坦地变化。对频率扫描天线能保证当波束扫描时,可以保持一个相对稳定不畸变的辐射方向图。 A new antenna structure consists of modified suspended substrate microstrip line with multilayer dielectric is proposed for getting desirable leaky characteristics. It is demonstrated that a suitable choice of the structure dimension can guarantee the antenna working in the antenna-mode region to make the antenna operate in an efficient way. Besides, very flat variation of the leakage constant with frequency can be achieved. It is a property for practical application as a frequency scanning antenna since it ensures a stable radiation pattern with little distortions while beam is being scanned.
