...A transmitting antenna converts the energy of an electric circuit into electromagnetic wave energy and radiates it into space, while a receiving antenna absorbs electromagnetic wave energy and converts it into electric circuit energy. The word "antenna" originally meant the antennae of insects and has no relation to the shape or location of installation, but since most early antennas were conductors stretched in the air, they were called "aerials" in English and "tensen" in Japanese. However, many modern antennas are not linear, so the term "tensen" has become inappropriate. *Some of the terminology that mentions "aerial" is listed below.

…電気回路のエネルギーを電磁波のエネルギーに変換して空間に放射するのが送信アンテナであり,逆に電磁波のエネルギーを吸収して電気回路のエネルギーに変換するのが受信アンテナである。アンテナantennaは,元来昆虫などの触角を意味する語であって,形状,設置場所などには関係のないものであるが,初期のアンテナの大部分が空中に張られた導線であったため,英語ではエアリアルaerial,日本語では空中線と呼ばれた。ところが,最近のアンテナには線状でないものが非常に多く,空中線という用語が不適当なものとなってきた。… ※「aerial」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
