antenna radiation impedance的意思|示意

The electric characteristic parameters of this novel sleeve antenna are calculated, including the input impedance, voltage standing wave ratio (VSWR), horizontal gain and radiation pattern.

研究了这种新型套筒天线的输入阻抗、电压驻波比（VSWR）、增益及辐射方向图等电特性。

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。

The small-size wide-band antenna (103) further includes a stub conductor (17) as an impedance matching unit for matching the impedance between the radiation element and the power supply means.

小型宽带天线（103）还包括作为在辐射元件和电力供应单元 之间进行阻抗匹配的阻抗匹配单元的短截线导体（17）。

Combination of ladder approach method and equivalent circuit model of slot antenna had been used to analyze its input impedance. Finally, GTD had been used to calculate the radiation pattern.
