Abstract
Description
図1は、実施の形態1に係るアンテナ装置における第1の例の構成を示す正面図である。図1では、誘電体基板1上にマイクロストリップアレーアンテナを構成した場合を例示している。
図5は、実施の形態2に係るアンテナ装置の構成を示す正面図であり、実施の形態1に係るアンテナ装置の構成と同一または同等の部分には同一の符号を付して示している。
実施の形態3では、実施の形態1のアンテナ装置における給電回路について説明する。ここでは、まず、表1に示した第1のケース(ナルフィリングなし)の振幅分布を与える給電回路3の構成例を説明する。この構成例による給電回路3は、図6に示すように、3個の電力分配器31,32,33から構成される。第1の電力分配器である電力分配器31は、図7に示すように0.707:1:0.707の電力分配比を有する不等3分配器である。すなわち、配列の中央に位置する放射素子23への電力を“1”(相対値、以下同じ)とすると、放射素子23から見て配列の一方側に位置する放射素子21,22からなる放射素子群に対しては“0.707”の大きさの電力を分配し、放射素子23から見て配列の他方側に位置する放射素子24,25からなる放射素子群に対しても“0.707”の大きさの電力を分配する。
