Quad 5G NR MIMO antenna array with transmission lines

A 5G NR MIMO antenna array, comprising:

• a planar ground substrate;
• the planar ground substrate configured to extend along a longitudinal plane and having a proximal end and a distal end opposite the proximal end, and the planar ground substrate further comprising a first side and a second side opposite the first side such that the proximal end, the distal end, the first side and the second side form a boundary of the planar ground substrate;
• a first and a second antenna each mounted to the planar ground substrate, one of the first and second antennas being disposed on the first proximal end and the other of the first and second antennas being disposed on the first distal end;
• a third antenna,
• the third antenna electrically coupled to the first side of the planar ground substrate by a first coaxial transmission line, the third antenna being configured to traverse the longitudinal plane;
• a fourth antenna,
• the fourth antenna electrically coupled to the second side of the planar ground substrate by a second coaxial transmission line, the fourth antenna being configured to traverse the longitudinal plane;
• characterized in that:
• each of the first through fourth antennas is independently oriented in an orthogonal relation with respect to two other antennas of the first through fourth antennas;
• and
• wherein the third antenna and the fourth antenna are each positioned with respect to the longitudinal plane to form independent angles comprising between and inclusive of negative eighty-nine degrees and positive eight-nine degrees.
