Abstract
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.
