How Does a Dipole Antenna Work?
Composition Dipole antennas are composed of two parallel wires. The wires produce a magnetic field that attracts the electrons being broadcast from another antenna. The open circuit of the two parallel wires is closed by the radiation of electrons around the wires. The two wires of a dipole antenna are required to produce the radiation–the two wires give the electrons a return path. Dipoles and monopole differ in that a monopole is a single wire. And like the partnership of the two dipole wires, the monopole needs a partner to produce a magnetic field–it uses a ground or “spike” antenna. Reception Radio frequency (RF) signals create a magnetic field around the transmitting signal, and the fluctuating signal of the transmitting antenna is received by the receiving antenna. An inverse of the transmitting field is produced around the receiving antenna to attract the broadcast. The quickly fluctuating RF signals received by the antenna are converted into electrical pulses and eventually
