Abstract
An antenna that is suitable for multiband operation. The antenna includes a plurality of first radiating elements configured to radiate in a first frequency band. The first radiating elements are arranged in a sparse mMIMO array. The antenna further includes a plurality of second radiating elements configured to radiate in a second frequency band lower than the first frequency band. The second radiating elements are arranged in an array at least partially overlapping with the sparse array. At least some of the second radiating elements are disposed in an area covered by the sparse mMIMO array.
Claims19
An antenna comprising:
- a plurality of first radiating elements configured to radiate in a first frequency band, the first radiating elements being arranged in a sparse massive Multiple Input Multiple Output (mMIMO) array;
- and
- a plurality of second radiating elements configured to radiate in a second frequency band lower than the first frequency band, the second radiating elements being arranged in an array at least partially overlapping with the sparse mMIMO array so that at least some of the second radiating elements are disposed in an area covered by the sparse mMIMO array,
- wherein:
- the plurality of the second radiating elements comprises first-type radiating elements and second-type second radiating elements, and
- the first-type second radiating elements are arranged in the area covered by the sparse mMIMO array and the second-type second radiating elements are arranged outside of the area covered by the sparse mMIMO array.
An antenna comprising:
- a plurality of first radiating elements configured to radiate in a first frequency band, the first radiating elements being arranged in a sparse massive Multiple Input Multiple Output (mMIMO) array;
- and
- a plurality of second radiating elements configured to radiate in a second frequency band lower than the first frequency band, the second radiating elements being arranged in an array at least partially overlapping with the sparse mMIMO array so that at least some of the second radiating elements are disposed in an area covered by the sparse mMIMO array,
- wherein:
- the sparse mMIMO array comprises the first radiating elements arranged along a longitudinal direction of the antenna in a plurality of columns separated along a lateral direction of the antenna, and
- at least one of the plurality of columns of the first radiating elements comprises fewer of the first radiating elements than other columns of the first radiating elements.
An antenna comprising:
- a plurality of first radiating elements configured to radiate in a first frequency band, the first radiating elements being arranged in a sparse massive Multiple Input Multiple Output (mMIMO) array;
- and
- a plurality of second radiating elements configured to radiate in a second frequency band lower than the first frequency band, the second radiating elements being arranged in an array at least partially overlapping with the sparse mMIMO array so that at least some of the second radiating elements are disposed in an area covered by the sparse mMIMO array,
- wherein the second radiating elements are arranged along a longitudinal direction of the antenna in a column at least partially overlapping with the sparse mMIMO array.
