Abstract
The invention relates to the mobile communication antenna field. A nested circular ring type dual polarization radiating element comprises a radiating body, baluns, feed pieces, a baffle board and a medium gasket. The radiating body comprises four oscillator arms which are identical in shape and distributed in central symmetry. The radiating body is in a circular ring shape and is nested with four small circular rings. Two identical uploading sections are arranged on the lower end of each oscillator arm. The baluns are in a pillar conductor structure, not only plays the role of supporting and fixing radiating body, but also plays the role of imbalance-balance transformation due to two-two symmetry. The feed pieces are arc-bridge shaped. Two feed pieces are orthogonally arranged. If the frequency range is 1710 megahertz to 2170 megahertz, the voltage standing wave ratio is smaller than or equal to 1.2, and isolation degree is larger than or equal to 32.4 d B.
