The invention relates to an antenna array for transmitting and receiving RF radiation to and from a target at a predetermined depth in an object. The antenna array can be used in a magnetic resonance image system. The antenna array is provided with at least one dipole antenna (401) comprising two legs, and each leg comprises at least two segments (401, 420 404, 405) and a coupling device (406, 407) arranged to electrically connect the respective segments.
