20120133569 | ANTENNA ARRAY - An antenna array and a method are disclosed. The antenna array comprises: a plurality of active antenna elements, each active antenna element being separated by a predetermined first spacing distance; and a plurality of passive antenna elements, each passive antenna element being separated by a predetermined second spacing distance. By providing both active and passive antenna elements, multiple networks can be supported by the same antenna array. Providing a dual network antenna significantly simplifies base station provision since existing base station sites may be reused more readily. Also, the number of antenna arrays which need to be provided at those base stations sites may be significantly reduced, thereby reducing mast head congestion and also reducing mast head loadings since the mass of the dual antenna array and its wind loading characteristics will be significantly less than that of two separate antenna arrays. | 05-31-2012 |
20120262359 | INTERLACED MULTIBAND ANTENNA ARRAYS - 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. | 10-18-2012 |
