All these characteristics can extend frequency band , reduce antennaelectric size and improve impedance characteristics. In order to miniaturization ofantenna, impedance complete compensate and matching optimization of electricallysmall antenna are brought forward, and this method is applied to the discage antennas.

從阻抗特性和輻射特性的實(shí)測(cè)數(shù)據(jù)表明啊使劲c我高清在线观看，水加載單極振子天線的諧振頻率能很好地向低端下移超碰人妻久久，局部水加載單極圓錐天線在保持原有寬頻帶特性的前提下，以較少的效率損失實(shí)現(xiàn)了較大范圍向低頻區(qū)擴(kuò)展影音先锋熟女AV下载电影，即天線小型化欧美一级婬片日本高清视，這將為短波超短波波段天線進(jìn)一步的小型化設(shè)計(jì)提供很好的思路。

Especially, discage antennas havesmall electrical size. Discage antennas combine the structure of discone antenna andcone-shape monopole antenna, and make use of ultra-wide-band twin-feed matchingsets.
