Interlaced multiband antenna arrays
DCFirst Claim
1. An interlaced multiband antenna array having a plurality of antenna elements, wherein the multiband antenna array works simultaneously on a plurality of frequencies,the multiband antenna array being characterised in that the position of the elements in the array results from the juxtaposition of a plurality of mono-band arrays, wherein the number of mono-band arrays corresponds to the number of working frequencies of the multiband antenna array, the multiband antenna array employed a single multiband antenna in those positions of the multiband antenna array in which the positions of two or more elements of the mono-band arrays come together, wherein the single multiband antenna covers at least two working frequencies of the 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.
