Abstract

The embodiment of the invention provides a dipole antenna unit and a manufacturing method thereof. The method comprises: forming a feeder module, wherein the height of the feeder module is smaller than 1 / 4 of a centre wavelength; connecting at least two oscillator arms to one end of the feeder module, and connecting a metal reflector to the other end of the feeder module; and arranging a medium element between the oscillator arms to change a current distribution characteristic, wherein the medium element is on the same plane with the oscillator arms. The dipole antenna unit manufactured by the method of the embodiment of the invention has a reduced section height and ensures the bandwidth impedance of the dipole antenna unit. As the section height of the dipole antenna unit is reduced, the volume of an antenna is reduced greatly.

technical field [0001] The invention relates to antennas in the communication field, in particular to a dipole antenna unit and a manufacturing method thereof. Background technique [0002] The antenna is an energy conversion device in the mobile communication system. The electromagnetic wave signal emitted by the mobile station is converted into an electrical signal by the antenna for processing by the base station; reversely, the base station converts the electrical signal into an electromagnetic wave signal through the antenna for propagation in free space. The mobile station can receive electromagnetic wave signals, so as to realize the two-way communication of the communication system. With the development of communication technology, antenna miniaturization has become the development trend of base station antennas, and the concept of integrated antenna system, which integrates transceiver modules into antennas, also puts forward more urgent requirements for antenna min...
