Dipole antenna fed by planar balun

A dipole antenna comprising:

• a first radiation element and a second radiation element respectively corresponding to poles of the dipole antenna;
• at least one dipole support column configured to connect the first radiation element and the second radiation element and to fix a gap between the first radiation element and the second radiation element;
• a planar balun connected to the first radiation element and the second radiation element and configured to supply balanced signals to the first radiation element and the second radiation element or to synthesize balanced signals received from the first radiation element and the second radiation element;
• and
• a balun housing coupled to the dipole support column and enclosing the planar balun.
