What is the size of antenna |
| Answer» An\xa0antenna\xa0– usually 1/2 wavelength long – split at the exact center for connection to a feed line. Dipoles are the most common wire\xa0antenna. Length is equal to 1/2 of the wavelength for the frequency of operation.\xa0In an instructable, the\xa0formula\xa0for\xa0calculating antenna length\xa0was given as "length\xa0in meters =300 / frequency in MHz". The example given was for a Bluetooth\xa0antenna\xa0with a frequency of 2450MHz. The\xa0antenna length\xa0was\xa0calculated\xa0as 300/2450 = 0.1225m = 12cm. | |
