A bi-polarized broadband annular radiation unit, for being installed on a metal reflective plate thus constituting a communication antenna and defining an annular construction by two pairs of orthogonally polarized dipoles, includes two pairs of orthogonally polarized dipoles, each dipole comprising two symmetrical unit arms of a single line sheet shape, one end of a unit arm being facing to a corresponding end of the other unit arm, and a distal end of each unit arm of at least one pair of dipoles is provided with a loading line; and a plurality of balun arms feeding power to and supporting respective dipoles, each balun arm including two parallel balun lines, and the top ends of the two balun lines being connected with corresponding ends of the two unit arms of a corresponding dipole. Each unit arm and the balun line and/or loading line connected to the same unit arm are made by sheet metal stamping forming process or casting process.

Bi-polarized broadband annular radiation unit and array antenna

A multi-frequency shared antenna comprises a low frequency radiation array and a first high frequency radiation array both of which are disposed on a reflection plate and provided with power by different feeding networks. The first high frequency radiation array comprises a number of high frequency radiation units, at least partial high frequency radiation units are arranged on a same axis which overlaps one of two axes of the low frequency radiation array, in all high frequency radiation units arranged on said axis, at least partial high frequency radiation units are nested with the low frequency radiation units arranged on the same axis, and the orthogonal projection area of these nested high frequency radiation units on the reflection plate falls within the orthogonal projection area of the corresponding low frequency radiation units on the same reflection plate.
