Description
本出願は、出願人同一の同時継続中の米国特許出願第10/940,206号、タイトル「RECONFIGURABLE RADIATION DESENSITIVITY BRACKET SYSTEMS AND METHODS」と関連し、該出願の全体が参考として本明細書において援用される。
本発明は、概して無線通信に関し、より詳細には無線通信アンテナに関する。
図14Aおよび図14Bは、本発明のブラケットが、接地板に放射により誘起された電流を再分配する状況を示す図である。垂直方向の大きさは電流(I)を示す。面積(unit2)あたりの電流、例えば、A/in2は電流または電流再分配の1つの可能な尺度である。しかしながら、他の測定値が本発明を明らかにするために使用され得る。図14Aにおいては、890MHzの放射発生源の結果として、比較的高い電流がある特定の領域に示されている。図14Bに示されるように、ブラケット108を可能化することに応答して、電流が再分配される。異なる電気的長さがいろいろな放射周波数に対して使用され得るので、ブラケットは周波数再構成可能であると考えられ得る。あるいは、電流を接地板のいろいろな領域に再分配するために利用され得るので、ブラケットは空間的に再構成可能であるとも考えられ得る。例えば、デバイスが物体の近くに移動された後に、電流を再分配(図14Aに示されるように)するようにブラケット108は調整され得、図14Bに示される電流パターンを作り得る。
