MULTI-BAND ANTENNA

WIPO Patent Application WO/2015/068962

A1

The present invention relates to a multi-band antenna, which comprises: a first antenna array of a first band configured by a radiation module of the first band; a (2-1)th antenna array of a common band between a second band and third band, the (2-1)th antenna array including radiation modules for the common band between the second band and third band; a (2-1)th phase shifter for receiving an input signal of the second band, distributing signals having phase difference therebetween to pre-configured radiation modules or groups of multiple radiation modules among the radiation modules of the (2-1)th antenna array, respectively, and then providing the signals; a (3-1)th phase shifter for receiving an input signal of the second band, distributing signals having phase difference therebetween to pre-configured radiation modules or groups of multiple radiation modules among the radiation modules of the (2-1)th antenna array, respectively, and then providing the signals; a plurality of (2-1)th frequency combiners for combining one pre-configured signal among output signals of the (2-1)th phase shifter with one corresponding signal among output signals of the (3-1)th phase shifter, and providing a combined signal to each pre-configured radiation module among the radiation modules of the (2-1)th antenna array or a pre-configured group among groups of multiple radiation modules among the radiation modules of the (2-1)th antenna array.
