摘　　要：为满足宽带定向低剖面相控阵设计要求，提出了一种立体和平面结构、寄生单元和激励单元相结合、网络和阵列环境相结合的锥形复合定向新颖高增益偶极天线，其单元指标为增益约6～8dBi、阵面高度为0．135λmax，由该单元组成的阵列的计算结果表明：该天线可以满足3个倍频程、30°扫描要求，为实现低剖面定向超宽带天线提供一种技术路线，为超宽带系统应用提供了有力支持．In order to meet the needs of broadband low profile phased array design. a novel tapered composite directional miniature high gain dipole antenna in 3D pla- nar structure with gain index of 6-8dB i and front height of 0. 135 wavelength, is presented, which combines the parasitic and incentive units, and network and array environment. The calculation results show that the antenna can meet the require- ments of three-octave, 30° power sweep, which provides techniques for low profile orientaion ultra-wideband antenna, and gives supports for UWB system applica- tion.
