Description
[数学式]
ここで、nは整数、bは前記単位セルの前記幅、aは前記伝送線路の前記幅である。
図2及び図7に示すデザインにより、単位セルの傾斜角度が0(ゼロ)のメッシュ構造で1X2アレイアンテナを形成した。具体的には、ガラス(0.7T)誘電層の上面上に銀(Ag)、パラジウム(Pd)および銅(Cu)の合金(APC)を用いてメッシュ構造の電極層を形成し、誘電層の底面上にAPCを蒸着してグランド層を形成した。メッシュ構造に含まれる導電ラインの線幅が3μm、電極の厚さ(または高さ)が2000Åとなるように形成し、電極とグランド層の距離が380μmとなるように形成した。単位セルの幅を100μmに固定し、伝送線路の幅をそれぞれ300μm、260μmおよび340μmとして実施例1、比較例1及び比較例2を形成し、28GHzにおけるアンテナ利得を測定した。その結果を表1に示す。
図2及び図8に示すデザインにより、単位セルの傾斜角度が4度のメッシュ構造で1X2アレイアンテナを形成した。具体的には、ガラス(0.7T)誘電層の上面上に銀(Ag)、パラジウム(Pd)および銅(Cu)の合金(APC)を用いてメッシュ構造の電極層を形成し、誘電層の底面上にAPCを蒸着してグランド層を形成した。メッシュ構造に含まれる導電ラインの線幅が3μm、電極の厚さ(または高さ)が2000Åとなるように形成し、電極とグランド層の距離が380μmとなるように形成した。単位セルの幅を100μmに固定し、伝送線路の幅をそれぞれ300μm、260μmおよび340μmとして実施例2、比較例3及び比較例4を形成し、28GHzにおけるアンテナ利得を測定した。その結果を表2に示す。
