Field symmetry, reflected in the design of antennas

Antenna possesses geometric properties that characterize the quality of resonance, antenna has a main purpose: to increase the probability of the observed sharp resonance. Spherical, conical symmetry, cylindrical, coaxial symmetry, the symmetry of plane and the square are the main types of symmetry, which characterize the change in the field and can be used in various combinations for constructing a spatial structure of antennas. Thus, it turns out that in the constructions is enough use of separate fragments of symmetry.
