ARRAY ANTENNA OPTIMIZED FOR BASE STATION COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an antenna in which some radiators are shared for multiple frequency bands.SOLUTION: The antenna includes: at least one first radiator for a first frequency band; one or more second radiator for a second frequency band; and a third radiator. Here, the third radiator is used not only when realizing the first frequency band but also when realizing the second frequency band.
