Lambda/4 antenna

Tīmeklis2014. gada 5. okt. · At the quarters or 1/4 (90 degrees) and 3/4 (270 degrees) wavelength the current is the highest and the radiation is greatest. 1 quarter wavelength is the shortest antenna length that will radiate signal. 3/4 and 1 1/4 and 1 3/4 and so on are also radiation points. Especially on receive the more length the better. TīmeklisA receiving antenna is one, which converts electromagnetic waves from the received beam into electrical signals. In two-way communication, the same antenna can be used for both transmission and reception. Antenna can also be termed as an Aerial. Plural of it is, antennae or antennas.
