The works of this paper are mainly about the study for ultra wide - band ( uwb ) signal radiating - designing for effective uwb antenna , and uwb signal scattering - investigating of composite scattering for targets upon ground . firstly , the radiating characters of uwb signal and development of uwb antenna are discussed an uwb planar horn antenna is designed this antenna is characterized with u - balun , simple construction and perfect performance 本文的研究是“九五”国防预研“超宽带( uwb )雷达体制及关键技术研究”项目工作的一部分，主要包括两方面内容：超宽带信号的辐射-高效超宽带天线的研制；超宽带信号的散射-地表目标的复合散射研究。

According to the application background and the dismatch between single antenna and differential lna , an active balun is needed and has been designed . then we put forward a design scheme that does co - simulation of an active balun and a differential lna on one chip together . at 2 . 45ghz , this lna provides a forward gain of 28 . 931db with a noise figure of 2 . 485db , while drawing 19 . 1ma from a 1 . 8v supply 从本设计的应用背景出发,考虑到单端天线与差分lna之间的不匹配性,设计了一个介于两者之间的有源平衡转换电路? balun ( balance - unbalunce ) ,并提出了将这个balun电路与前面设计的差分lna作为一个整体进行了仿真的设计方案。
