Description
本出願は、2006年8月25日に出願された「Broadband and Compact Multiband Metamaterial Structures and Antennas」という表題の米国仮特許出願第60/840,181号、及び2006年9月22日に出願された「Advanced Metamaterial Antenna Sub-Systems」という表題の米国仮特許出願第60/826,670号の利益を主張するものである。
二次元構造では、それぞれのセルは、集中素子Zx(nx,ny)、Zy(nx,ny)、及びY(nx,ny)並びにすべての終端Ztx(1,ny)、Ztx(Nx,ny)、Zt(nx,1)、及びZt(nx,Ny)の異なる値により特徴付けることができ、給電は不均一である。このような構造は、ある種のアプリケーションに適した固有の特性を持つことがあるけれども、その解析は、複雑であり、実装は、対称性の高い構造に比べて実用性を大きく欠いている。これは、もちろん、共振周波数を中心とする帯域幅拡張を利用することに加えてなされる。本出願の二次元構造の実施例は、それぞれx方向、y方向にそって、またシャントを通して、等しいZx、Zy、及びYを持つCRLH MTMユニットセルに対するものである。CRの異なる値を持つ構造も、さまざまな応用例で使用されうる。
図5は、四つのユニットセルに基づく一次元CRLH材料TLの一実施例を示している。四つのパッチが、誘電体基板の上に置かれ、センタリングされたビアがグラウンドに接続される。図6は、図11のデバイスの類似している等価回路網を示している。ZLin'及びZLout'は、それぞれ入力及び出力負荷インピーダンスに対応し、それぞれの端部のTLカップリングによるものである。これは、プリントされた2層構造の一実施例である。図2A〜2Cを参照すると、図5と図6との対応関係が例示されており、(1)ではRH直列インダクタンス及びシャントキャパシタは、パッチとグラウンド面との間に誘電体がサンドイッチ状に挟まれていることによるものである。(2)では、直列LHキャパシタンスは、二つの隣接するパッチが存在することによるものであり、ビアは、シャントLHインダクタンスを誘導する。
周波数帯域は、N個のCRLHセル構造を、n=0、±1、±2、...±Nに対するnπの伝搬位相長で共振させることにより導出された分散式から決定される。N個のCRLHセルはそれぞれ、式II-1-2においてZ及びYにより表され、CLが末端セルから欠落している図6に示されている構造と異なる。したがって、これら二つの構造に関連する共振は異なるものと予想できるであろう。しかし、大量の計算の結果から、すべての共振はn=0の場合を除き同じであり、ωSEとωSHは両方とも、第1の構造で共振し、ωSHのみが、第2の構造で共振することが示される(図6)。正の位相オフセット(n>0)は、RH領域共振に対応し、負の値(n<0)は、LH領域に関連する。
すでに示されているように、分散曲線勾配が急勾配値になると、次のステップは、好適なマッチングを識別することである。理想的なマッチングインピーダンスは、固定値を有し、マッチング回路網に広いフットプリントを必要としない。ここで、「マッチングインピーダンス」という語句は、アンテナなどの片側給電の場合の給電路及び終端を指す。入出力マッチング回路網を解析するために、図9AのTL回路についてZin及びZoutを計算する必要がある。図8の回路網は対称的なので、Zin=Zoutという条件は満たされる。それに加えて、Zinは、式
CRLH MTM構造では、LH共振の帯域幅を増大するために、シャントキャパシタCRを低減することができる。この低減により、式II-1-8に説明されているようにより急な勾配を持つβ曲線のωR値が高くなる。CRを下げるさまざまな方法があり、1)基板厚さを増す、2)上部セルパッチ面積を減らす、又は3)上部セルパッチの下のグラウンド電極を縮小する方法を含む。CRLH MTMデバイスを設計する際に、これら三つの方法のうちの一つを他の一つ又は二つの方法と併用するか、又は組み合わせて、所望の特性を有するMTM構造を形成することができる。
上記CRLH MTM構造設計は、基板の片側にグラウンド電極として完全導体(PEC)を使用することに基づく。PECグラウンドは、基板面全体を覆う金属層とすることができる。上記の実施例に示されているように、PECグラウンド電極を、寸法が基板面よりも狭くなるように切断して、アンテナ共振の帯域幅を増やすことができる。上記の実施例では、切断PECグラウンド電極は、基板面の一部を覆うように設計することができるが、MTMセルのフットプリントには重ならない。このような設計では、グラウンド電極ストライプ線は、セルビアと切断PECグラウンド電極を接続するために使用できる。MTMアンテナ構造の下のGND平面のこのような縮小を用いてRH静電容量C_Rを小さくし、それと対になるLH静電容量C_Lを大きくする。その結果、共振の帯域幅を増やすことができる。PECグラウンド電極は、MTM構造の金属グラウンド平面を形成する。金属グラウンド平面は、完全磁性体平面又は完全磁性体(PMC)構造の表面により置き換えることができる。PMC構造は、合成物質構造であり、天然には存在しない。PMC構造は、実質的に広い周波数範囲にわたってPMC特性を示しうる。PMC構造の実施例は、「High-Impedance Electromagnetic Surfaces」(カリフォルニア大学(ロサンゼルス所在)博士学位論文)(1999)においてシーベンパイパー(Sievenpiper)が説明している。以下の節では、CRLH MTM構造とPMC構造の組合せに基づくアンテナ及び他の応用向けのMTM構造について説明する。MTMアンテナは、MTM構造の下にPEC平面の代わりにPMC平面を入れるように設計されうる。HFSSモデルに基づく初期調査により、このような設計は、一次元と二次元の両方の構成におけるMTMアンテナ用に金属GND平面を持つMTMアンテナよりも大きいBWを実現できることが確認されている。したがって、MTMアンテナは、例えば、第1の側に第1の表面を、第1の側と反対側の第2の側に第2の表面を有する誘電体基板、第1の表面上に形成された少なくとも一つのセル導電性パッチ、第2の表面と接触するPMC表面をサポートするように基板の第2の表面上に形成されたPMC構造、及び導電性パッチをPMC表面に接続してCRLH MTMセルを形成する
ように基板内に形成された導電性ビアコネクタを備えることができる。第2の基板は、PMC構造をサポートするために使用することができ、この基板と係合して、MTMアンテナを構成する。
