Abstract
An antenna array includes one or more substrates and four individual antennas in a slant formation to improve radiation pattern independence. In various embodiments, a novel slanted antenna array configuration is disclosed where one of the four antennas is orthogonal to two of the remaining three antennas. In some embodiments, two separate substrates and a tapered dielectric spacer are used to provide a larger variety of slant formations.

A 5G NR MIMO antenna array, comprising:
- a first planar substrate,
- the first planar substrate configured to extend along a first longitudinal plane and having a first proximal end and a first distal end opposite the first proximal end;
- a second planar substrate,
- the second planar substrate configured to extend along a second longitudinal plane and having a second proximal end and a second distal end opposite the second proximal end;
- a first antenna and a second antenna each coupled to the first planar substrate, one of the first and second antennas being disposed at the first proximal end and the other of the first and second antennas being disposed at the first distal end;
- a third antenna and a fourth antenna each coupled to the second planar substrate, one of the third and fourth antennas being disposed at the second proximal end and the other of the third and fourth antennas being disposed at the second distal end;
- and
- a dielectric tapered spacer configured to be disposed between each of the first and second planar substrates thereby forming an angle between the first longitudinal plane and the second longitudinal plane, respectively, the angle comprising between and inclusive of one and eighty-nine degrees.
