Description
C=ε0×εr×S/d ------------- (式1)
検査台11にアンプ一体型アンテナ20を密着固定した状態では、各アンテナエレメント21,31の放射素子22,32,無給電素子23,33の相当面積が等価コンデンサ61の各電極62,63の面積に相当し、検査台11と各アンテナエレメント21,31を覆う各防水フィルム24,34の合成比誘電率が比誘電率εrに相当し、検査台11の厚さと各防水フィルム24,34の合計厚さが誘電体の厚さdに相当する。このことから、検査対象のアンプ一体型アンテナ20を検査台11に密着固定した場合の図4の回路に示す等価コンデンサ61の容量Cはあらかじめ計算しておくことができる。
