摘要： An antenna system includes: a first antenna element configured to transduce between second wireless energy and second transmission-line-conducted energy, wherein the first and second wireless energy are of first and second polarizations of the first antenna element and in first and second directions that are different and define a first plane; and a second antenna element configured to transduce between third wireless energy and third transmission-line-conducted energy and between fourth wireless energy and fourth transmission-line-conducted energy, wherein the third and fourth wireless energy are of first and second polarizations of the second antenna element and in third and fourth directions that are different and define a second plane that is substantially orthogonal to the first plane.

摘要： An antenna assembly includes an array of patch antennas arranged above a rectangular ground plane. The patch antennas are arranged in a sequence beginning at a first end of the rectangular ground plane and continuing across a width of the rectangular ground plane to a second end. With regard to this sequence, a plurality of polarization feeds alternate between being adjacent a first corner to being adjacent a second corner of the patch antennas and/or a plurality of via walls alternate in orientation along portions of a first edge of the rectangular ground plane and along portions of a second edge of the rectangular ground plane.

摘要： Methods, systems, and devices for wireless communication are described. According to one or more aspects, the described apparatus includes one or more stacks of patch radiators (such as patch antennas) comprising at least a first patch radiator and a second patch radiator. The first patch radiator is associated with a low-band frequency; the second patch radiator is associated with a high-band frequency. The first patch radiator and the second patch radiator may overlap a ground plane, which may be asymmetric. Some or all patch radiators in a stack may be rotated relative to the ground plane, such that some or all edge of a patch radiator may be nonparallel with one or more edges of the ground plane. Further, each patch radiator stack may include separate feeds for each of at least two frequencies and two polarizations, and thus at least four feeds (one for each frequency/polarization combination) in total.
