Analysis of Millimeter Wave Monopulse Antenna/ Feed System 毫米波单脉冲天馈系统研究
The antenna design is based on using capacitive loads and slits on two crossed narrow patches with via fed-through feed system, which can reduce the size of the antenna, improve the isolation between two ports and keep considerable bandwidth respectively. 通过电容性加载减小整个天线的尺寸,通过在天线上开槽来增加天线端口之间的隔离度,采用viafed-through的馈电方式。
Feed network is an important part of shortwave multimode multifeed antenna system. The design of feed network is a pivotal technique in the process of projecting antenna system. To analyze its characteristics directly is very difficult. 馈电网络是短波多模多馈天线系统的重要组成部分,因此,馈电网络的设计是多模多馈天线系统设计的关键技术,直接分析其结构非常困难。
A microstrip array antenna is designed and manufactured to work as the feed of the Cassegrain antenna system. 研制了一个用作卡塞格伦天线系统的馈源的微带天线阵。
Integralization design in antenna and feed system of active phased array for low side lobe 低副瓣有源相控阵天馈系统中的一体化设计
For the antenna feeding, two kinds of Wilkinson power divider are designed. By comparing the performances and fabrication complexities, one of the power divider is selected as the element of the antenna feed system. 同时针对振子天线设计出两种威尔金森功率分配器,通过对比性能和加工复杂度,选择其中一种作为振子天线馈电系统的单元。
In order to achieve enough detection range and positioning accuracy, the phased array technology is often used in PCL systems. In this thesis, the sub-system of antenna and feed in PCL system which roots from an engineering practice are studied comprehensively. 为达到一定的探测距离和定位精度,相控阵天线技术常被用于无源相干定位系统中。
