Abstract
The utility model discloses a high-performance broadband bipolarized radiation element, which comprises two pairs of polarized orthogonal dipoles and a balancer for balanced feed for each dipole. Each dipole includes two unit arms with ends on one side mounted on the balancer symmetrically and fixedly; loaded lines are arranged at the other ends of the unit arms; each dipole is in an asymmetric fold line form relative to the balancer; the loaded line at the tail end of one unit arm is bent inwards; and the loaded line at the tail end of the other unit arm is bent downwards. The loaded lines of the dipoles are designed in the combined mode of bending inwards and bending downwards, so that the inwards bent loaded lines can be far away from a high-frequency oscillator sleeved between two low-frequency oscillators in an inlaid manner so as to decrease influence on the high-frequency oscillator. The downwards bent loaded lines effectively compensate asymmetry of bipolarization, so that cross bipolarization performance indexes are improved substantially. In addition, by the aid of the structural design, the high-performance broadband bipolarized radiation element has more advantages in terms of both cost and reliability.
