impedance-matching network

基本解释

The impedance matching network of changeable load and wide-belt is required because the input impedance of spiral antenna changes with frequency.
由于该天线的输入阻抗随频率而变化，需要用一个宽带变负载阻抗匹配网络来实现天线与电台之间的匹配。
The radiation patch, feed line, and the impedance-matching network are a coplanar structure which can be etched simultaneously; this helps to simplify the manufacturing process.
标签天线的辐射贴片、馈线和无源阻抗匹配网络是一个平面结构，加工时可以同时刻蚀，简化了工艺。
Balanced micro-strip line is utilized as feed line, printed dipole is adopted as radiation element, and a matching network is employed for tuning the input impedance of the antenna.
该天线采用平衡微带线作馈线，以印刷振子作为辐射单元，末端采用匹配电路对其输入阻抗进行匹配。
