Abstract
Description
本発明は、一態様において、電磁放射の送受信用アンテナに関する。このアンテナは、可撓性であり、アンテナをファブリック、布または別の材料に織り込んだり埋め込んだりすることを可能にし得る本体部分を含む。このアンテナは、更に、本体部分に沿う伸長ナノチューブの集合体も含む。一態様において、集合体は長さ数ナノメートルから1メートル以上までであり得る。集合体は、高周波数電磁放射、例えば100MHz超、を送受信し、バリスティック伝導を増大し、シグナル歪を最小化するために表面電流を最小化し、かつ/または本体部分に沿う熱痕跡を最小化するようにデザインされ得る。一態様において、集合体は、そこに分散された、集合体の一体性を維持するポリマー樹脂を含み得る。アンテナは、更に、隣接ナノチューブ間に複数の接点を含み、電磁放射の伝達を可能にし、一方、高周波数におけるアンテナの抵抗率を減らす。本発明のアンテナはループ、アレイ、または別の幾何学形態のように、形状が細長くデザインされ得る。
本発明のアンテナまたはセンサーの製造用のカーボンナノ構造体、例えば、カーボンナノチューブ、は、様々なアプローチを用いて製造され得る。現在、カーボンナノチューブの成長に関する複数のプロセスおよびそれらの変形が存在する。これらとしては、(1)周囲圧力に近い圧力または高圧において生じ得る一般的な方法である、化学蒸着(CVD)、(2)完全性の高いチューブを生じ得る高温プロセスである、アーク放電、および(3)レーザーアブレーションが挙げられる。
