The device has a two periodic linear arrangements of first (14) and second (15,16) individual antennas for two frequency bands. The period of the first arrangement is essentially twice that of the second. The second antennas are arranged alternately between and above the first antennas. The two antennas are patch radiators and each contains a printed plate and several stacked patch plates at intervals in a rectangular conducting open box. |
