Biconical Antennas have dipole like characteristics (e.g. circular directional pattern in the H-plane,"8"-shaped in the E-plane, fixed phase center, comparable gain), with an enormous wide bandwidth achieved by the double cone elements. 详细
Tuned half-wave dipoles have been among the most important antennas from the
beginning of rf-technique. The characteristics of half-wave dipoles have
been calculable very early using the Maxwell and Hertz equations. 详细
