窄頻軸 的英文怎麼說
中文拼音 [zhǎibīnzhóu]
窄頻軸
英文
narrow-band axis-
Secondly, because the band of the traditional microstrip antenna is very narrow. and the isolation can ’ t meet the requirement when the coaxial - line feeding is used to realize the dual polarization. the following work lays heavy stress on analysis of the way of widening the bandwidth and developing the isolation of the antenna
傳統的微帶天線帶寬較窄,採用普通同軸線饋電實現雙極化的時候,隔離度不能夠滿足天線的要求,所以在接下來工作中,重點分析了微帶天線頻帶展寬和隔離度改善的方法。However, in hf band, the band of the antennas is narrow, and the input impedance of monopole antenna with limited height undergoes rapid variation with frequency
但是,在hf頻段,有限高無加載單極子天線帶寬相對較窄,輸入阻抗隨頻率劇烈變化,難于和50的同軸饋線匹配。
