Abstract
The present invention relates to an antenna arrangement connectable to a transceiver for transmitting and receiving RF signals in at least two separate frequency bands. The antenna arrangement has at least two sets of antenna elements arranged on a reflector, and the antenna elements are arranged in an interleaved configuration along a single column. The two separate frequency bands are substantially non-overlapping but relatively close to each other, and the distance between adjacent antenna elements in said column is substantially the same along the column.
Claims19
An antenna arrangement connectable to a transceiver for transmitting and receiving RF signals in at least two separate frequency bands, said antenna arrangement having at least two sets of antenna elements in an interleaved arrangement on a reflector, wherein a first set of antenna elements is arranged in a column and operates in a first frequency region, whereas a second set of antenna elements is likewise arranged in a column and operates in a second frequency region, wherein said first and second sets of antenna elements are interleaved along and positioned in a non-overlapping configuration on a straight line so as to form a single column, said first and second frequency regions include first and second frequency bands, respectively, which are separate and substantially non-overlapping but relatively close to each other, and the distance (x) between adjacent antenna elements in said column, operating in different frequency bands, is substantially the same along said column and is smaller than the wavelength λ of the centre frequency of the highest one of said first and second frequency bands.
