aerial

Japanese: aerial
aerial

...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.

However, many modern antennas are not linear, so the term "tensen" has become inappropriate.

*Some of the terminology that mentions "aerial" is listed below.
