A half-wave dipole antenna is an omnidirectional antenna that is one of the basic types used in satellite communication. It has an impedance of 73 ohms and directivity and power gain of 2.15 dB when used under suitable conditions. The radiation of a half-wave dipole is maximum in the xy plane and its radiation pattern is described.
