Sketch a diagram an write a paragraph or two explaining how transmission and reception in antennas works. [Hint: your answer had better include f = qE as part of the description.]
Antennas transmit and receive electromagnetic waves. Generally composed of metals (mainly copper or aluminum), antennas can convert an electric current into electromagnetic radiation and vice versa. Every wireless communication device contains at least one antenna.Transmission antennas produce radiofrequency radiation that propagate in space.Receiving antennas perform the reverse process: they receive radiofrequency radiation and convert them into the required signals (e,g. sound, picture) in the receiving device (e.g., radio, television, mobile phone).
