了解天线的工作原理,尤其是手机天线的调试制作,并用网络分析仪和微波暗室对天线
的参数(Return loss,VSWR,Smith chart,gain,efficiency,E plane,H
Plane)进行测试和分析。除了对天线本身进行调试外,还能利用Smith
chart调试匹配电路。目前常调试的外置天线有螺旋天线,PCB板天线,内置较常见的为
PFIA天线和Planner monople.能用HFSS做一些简单的仿真。能用CMU200对手机进行TX
power,RX Level,sensitivity测试。
An antenna is an electrical conductor used in the transmission and
reception of electromagnetic energy by converting radio waves into
electrical signals
• Antenna design is becoming more demanding given the diversity of the
products they are used in and the different environments they are
found in.
• Antenna measurements are becoming more complex as 2D measurements are
no longer enough to determine if an antenna is good or bad. 3D
chambers are now available but onl……
