Patent ID: 7557768

Claim:
An interlaced multiband antenna array comprising: a plurality of antenna elements; wherein the interlaced multiband antenna array is operative simultaneously on a plurality of working frequency bands; wherein positions of the plurality of antenna elements result from juxtaposition of a plurality of mono-band antenna arrays, each mono-band antenna array of the plurality of mono-band antenna arrays comprises a plurality of mono-band antenna elements; wherein a number of the plurality of mono-band antenna arrays corresponds to a number of the plurality of working frequency bands of the interlaced multiband antenna array; wherein the interlaced multiband antenna array employs a single multiband antenna element in positions where mono-band antenna elements of a plurality of the plurality of mono-band antenna arrays come together; wherein the single multiband antenna element comprises a plurality of electromagnetically-coupled portions which are adapted to interact with each other to establish radio-electric characteristics of the single multiband antenna element with respect to radiation and impedance patterns that are similar in a plurality of the plurality of working frequency bands; and wherein a spacing between the mono-band antenna elements of each mono-band antenna array of the plurality of mono-band antenna arrays is between a half-wavelength and less than one wavelength of the working frequency band corresponding to the mono-band antenna array.
