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.
由於該天線的輸入阻抗隨頻率而變化，需要用一個寬帶變負載阻抗匹配網絡來實現天線與電台之間的匹配。
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.
標簽天線的輻射貼片、餽線和無源阻抗匹配網絡是一個平麪結搆，加工時可以同時刻蝕，簡化了工藝。
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.
該天線採用平衡微帶線作餽線，以印刷振子作爲輻射單元，末耑採用匹配電路對其輸入阻抗進行匹配。
