with a coaxial arrangement of the feeds

Arrangements for simultaneous operation of antennas on two or more different wavebands, e.g. dual-band or multi-band arrangements > Imbricated or interleaved structures; Combined or electromagnetically coupled arrangements, e.g. comprising two or more non-connected fed radiating elements > using two or more feeds in association with a common reflecting, diffracting or refracting device > with a coaxial arrangement of the feeds
