Antennas with polarization diversity

A multiple-input, multiple-output (MIMO) antenna system, comprising:

• at least one horizontally polarized antenna;
• and
• a vertically polarized antenna coupled to the at least one horizontally polarized antenna, wherein the at least one horizontally polarized antenna is coupled to the vertically polarized antenna by a printed circuit board connector element by fitting a portion of the printed circuit board connector element inside a rectangular slit formed within the printed circuit board of the at least one horizontally polarized antenna thereby allowing a radio frequency (RF) feed to traverse the at least one horizontally polarized antenna and the vertically polarized antenna.

A multiple-input, multiple-output (MIMO) antenna system, comprising:

• at least one horizontally polarized antenna;
• and
• a vertically polarized antenna coupled to the at least one horizontally polarized antenna, wherein the at least one horizontally polarized antenna is coupled to the vertically polarized antenna at an intersecting trace element in the printed circuit board of both the at least one horizontally polarized antenna and the vertically polarized antenna thereby allowing an RF feed to traverse the at least one horizontally polarized antenna and the vertically polarized antenna.

A multiple-input, multiple-output (MIMO) antenna system, comprising:

• a plurality of horizontally polarized antennas each including a plurality of antenna elements configured to be selectively coupled to a radio frequency feed port, wherein coupling a first antenna element and a second antenna element to the radio frequency feed port generates a substantially omnidirectional radiation pattern substantially in the plane of the horizontally polarized antennas;
• and
• a plurality of vertically polarized antennas coupled to the plurality of horizontally polarized antennas, wherein the plurality of vertically polarized antennas are configured to generate a radiation pattern substantially perpendicular to a radiation pattern generated by the plurality of horizontally polarized antennas, wherein each of the plurality of horizontally polarized antennas are coupled to one of the plurality of vertically polarized antennas by fitting each one of the plurality of vertically polarized antennas inside at least one rectangular slit formed within the printed circuit board of one of the plurality of horizontally polarized antennas.
