Description
Microwave Products,Advanced Circuit
Materials Division,100 S.Roosevelt
Ave,Chandler,AZ 85226から入手可能である。これらの材料の双方は一般的な基板材料の選択肢である。上記の基板材料は、厚さ及び物質的特性に関して、基板領域に亘って均一であり、付随的な低い損失正接を伴った比較的低い誘電定数を有する誘電層を提供する。これらの材料の双方の比誘電率は1に近い。
TapeTMと普通呼ばれる未処理材料は、バルクの誘電テープから6インチ×6インチ部分のような標準サイズ化された部分に切断され得る。例えば、DuPont
Microcircuit Materialsは951 Low−Temperature
Cofire Dielectric
TapeのようなGreen Tape材料システムを提供し、Ferro Electronic
Materials ULF28−30 Ultra Low Fire
COG誘電配合を提供している。一旦発射されたマイクロ波周波数での回路動作のために、付随する比較的低い損失正接を伴った比較的中程度の誘電定数を有する誘電層をもたらすよう、これらの基板材料を用い得る。
本発明に従って磁気粒子を含む誘電体を用いるインピーダンス整合を取扱う幾つかの特別の例が提示される。給電からスロットへのインピーダンス整合、並びに、スロット及び環境(例えば、空気)が実証される。
空気を上方に備えたスロット
図4を参照すると、上方に空気(媒体1)を有するスロットアンテナ400が示されている。アンテナ400は、送電線405と、接地平面410とを含む。接地平面410はスロット415を含む。εr=7.8を有する誘電体430が、送電線405と接地平面410との間に配設され、且つ、領域/媒体4と、領域/媒体3と、領域/媒体2とを含む。領域3は参照番号432によって指し示された関連する長さ(L)を有する。領域425はこの解析に余り影響を及ぼさないと考えられ、よって、ここでは無視されている。何故ならば、それは関心のある物理的処理を説明するためには不必要な追加的な複雑さを加えるからである。
誘電体を上方に備えるスロット。誘電体は1の比透磁率及び10の誘電定数を有する。
誘電体を上方に備えるスロット。誘電体は、10の比透磁率と、20の誘電定数とを有する。
