Interlaced multiband antenna arrays

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.

1 . Interlaced multiband antenna arrays which works simultaneously on various frequencies characterised in that the position of the elements in the array is obtained from the juxtaposition of as many mono-band arrays as there are working frequencies required, employing a single multiband antenna, capable of covering the different working frequencies, in those positions of the array in which the positions of two or more elements of the mono-band arrays come together.
