Abstract
Description
1)同じ振幅の直交線形偏光があって、90°の位相シフトを表す、2つの波の2つの点での励起(例えば、THOMSON multimediaによる特許文献1参照。)によって;及び
2)1つの点での励起;
によって得ることが可能であり、円形偏光の生成は励起点から45°にある平面におけるノッチ又は突起のような摂動をもたらすことによって得られる。
2つの結合点間のスロットの長さは、λsがスロットにおける導波路伝搬波長で、スロットの周辺長がλsの場合、おおよそ、λs/4、すなわち、スロットの周辺長の1/4、であり;
2つの結合点の間の線の長さは、λmが給電線下の導波路伝搬波長で、k’が奇整数の場合、おおよそ、k’λm/4であり;かつ
給電線の終端と第1結合点との間の長さは、λmが給電線下で、開回路で終端する、導波路伝搬波長の場合、おおよそ、λm/8 mod λm/2となる。
環状スロットは内直径φin=12.6並びに外直径φex=13及びインピーダンスZs=108.5Ωを表す;
を有する。マイクロストリップ手法によって形成された給電線13は、特性インピーダンスZm=134.5Ω、0.2mmの幅を表し、環状スロットを接点から離れた所で1.895mmの線に並行して交差する。この場合、シミュレーション結果を図3に表す曲線によって反射係数S11について表す。−10dBでは、動作周波数の19.8%に相当する周波数帯、すなわち、従来システムよりも大きな周波数が得られ、欧州及び米国標準に準拠することが可能になることがわかるものである。
