において、誘電体あるいは導体の枠の間に格子状
の金属パターンを配置し、上記金属パターンの一
端を形状記憶合金製の固定板に固定し、他端の弾
性体により上記金属パターンに張力をかけたこと
を特徴とする周波数選択板。 In a frequency selection plate that separates high-frequency and low-frequency radio waves, a grid-like metal pattern is arranged between a dielectric or conductor frame, one end of the metal pattern is fixed to a fixed plate made of shape memory alloy, and the other end is fixed to a fixed plate made of shape memory alloy. A frequency selection board characterized in that tension is applied to the metal pattern by an elastic body at the end.
