impedance-matching network

基本解釋

The impedance matching network of changeable load and wide-belt is required because the input impedance of spiral antenna changes with frequency.
由于該天線的輸入阻抗隨頻率而變化，需要用一個(gè)寬帶變負(fù)載阻抗匹配網(wǎng)絡(luò)來(lái)實(shí)現(xiàn)天線與電臺(tái)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(biāo)簽天線的輻射貼片、饋線和無(wú)源阻抗匹配網(wǎng)絡(luò)是一個(gè)平面結(jié)構(gòu)，加工時(shí)可以同時(shí)刻蝕，簡(jiǎn)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.
該天線采用平衡微帶線作饋線，以印刷振子作為輻射單元，末端采用匹配電路對(duì)其輸入阻抗進(jìn)行匹配。
