Antenna array arrangement for a multi band antenna, comprising a plurality of first dual band antenna elements adapted for transmitting/receiving in a lower antenna frequency band and in a higher antenna frequency band, a plurality of first single band antenna elements adapted for transmitting/receiving in the higher antenna frequency band, the first dual band antenna elements and the first single band antenna elements being arranged in a row, wherein at least two first single band antenna elements are arranged adjacent to each other. Furthermore, the invention also relates to a multi band antenna comprising at least one such antenna array arrangement.

Antenna array arrangement and a multi band antenna

The present invention relates to a reflectorfor use in an antenna. The reflectoris arranged to be used as an earth plane of the antennaand the reflector is corrugated to form current pockets. The reflectorcomprises at least two separate parts, and the parts are electrically coupled to each other to commonly form the earth plane of the antenna. The invention also relates to an antenna including a reflector, and to a method for manufacturing a reflector.

Reflector, an antenna using a reflector and a manufacturing method for a reflector

An antenna assembly and a method of mounting such an assembly are disclosed. A first and a second assembly portion are joined together, wherein the assembly portions each comprise a elongated reflector body serving as a reflector for electromagnetic power radiated by the antenna assembly portion, and a set of antenna element receiving means located in a linear row along a longitudinal direction of the reflector body for respectively receiving an antenna element, and side portions along the long sides of the said reflector body. The assembly method comprises the step of fastening the first and second assembly portions to each other along a respective side portion of the said assembly portions so as to form a dual array antenna assembly.

Antenna assembly

The present invention relates to an antenna arrangement comprising a first and third set of antenna elements, being arranged as a first and third column and aligned along a first and third symmetry axis, respectively, each column comprising elements being operative in a first frequency band (f) and elements being operative in a second frequency band (f). The antenna arrangement further comprises a second set of antenna elements, being arranged as a second intermediate column along a second symmetry axis, said second symmetry axis being parallel to said first and third symmetry axes, and being operative in said second frequency band (f), wherein the ratio of said second center frequency (f) to said first center frequency (f) is in the range 1.5 to 3. The distance between said first and third symmetry axes is less than or equal to 0.6 times the wavelength of said first center frequency (f), and the distance between said second and said first and third symmetry axis, respectively, is less than or equal to 0.6 times the wavelength of said second center frequency (f).

Dual band antenna arrangement

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.
