Interlaced multiband antenna arrays
DCFirst Claim
1. An interlaced multiband antenna array comprising:
- a plurality of antenna elements;
wherein the interlaced multiband antenna array is adapted to operate simultaneously on a plurality of frequency bands;
wherein positions of the plurality of antenna elements result from juxtaposition of a plurality of mono-band antenna arrays;
wherein the number of the plurality of mono-band antenna arrays corresponds to the number of working frequency bands of the interlaced multiband antenna array;
wherein the interlaced multiband antenna array employs a single multiband antenna element in positions wherein a plurality of antenna elements of the mono-band antenna arrays come together; and
wherein the single multiband antenna element covers at least two working frequency bands of the interlaced multiband antenna array.

Abstract
Antenna arrays which can work simultaneously in various frequency bands thanks to the physical disposition of the elements which constitute them, and also the multiband behaviour of some elements situated strategically in the array. The configuration of the array is described based on the juxtaposition or interleaving of various conventional mono-band arrays working in the different bands of interest. In those positions in which elements of different multiband arrays come together, a multiband antenna is employed which covers the different working frequency bands. The advantages with respect to the classic configuration of using one array for each frequency band are: saving in cost of the global radiating system and its installation (one array replaces several), and its size and visual and environmental impact are reduced in the case of base stations and repeater stations for communication systems.
