Description
縦列アンテナ15b、15c、及び15dによる間引きアレイ15.2は、当該間引きアレイ15.2内での縦列アンテナ15b、15c、及び15dの互いの所定間隔の量が、縦列アンテナ15aの同一のアンテナ開口及び同一の特性を備える平面アンテナ装置の図1の対応する非疎なアレイ15.1の2つの任意の縦列アンテナ15a間の様々な間隔の全てを少なくとも一度、しかし可能な限り最小の数となるように、最小の冗長性を備えて実現される。その際に、図3から更に分かるように、縦列アンテナ15bと15cとの間には、空中の波長0.5λの間隔が設けられ、縦列アンテナ15cと15dとの間には、空中の波長1.0λの間隔が設けられる。更に、縦列アンテナ15bと15dとの間は、間隔が空中の波長1.5λのままである。
