Patent ID: 8780002

Claim:
A MIMO antenna comprising: a first radiating element that includes a straight portion connected to a serpentine portion, wherein the straight and serpentine portions are configured to resonate in at least two spaced apart RF frequency ranges in response to the straight portion being electrically excited through a first RF feed, and wherein the straight portion of the first radiating element separates the first RF feed from the serpentine portion thereof; a second radiating element that includes a straight portion connected to a serpentine portion, wherein the straight and serpentine portions are configured to resonate in at least two spaced apart RF frequency ranges in response to the straight portion being electrically excited through a second RF feed, and wherein the straight portion of the second radiating element separates the second RF feed from the serpentine portion thereof; a conductive neutralization line that connects the first and second radiating elements to conduct resonant currents therebetween that at least partially cancel RF transmission coupling between the first and second radiating elements; a third radiating element that includes a straight portion connected to a serpentine portion, wherein the straight and serpentine portions are configured to resonate within at least two spaced apart RF frequency ranges in response to the straight portion being electrically excited through a third RF feed; a fourth radiating element that includes a straight portion connected to a serpentine portion, wherein the straight and serpentine portions are configured to resonate within at least two spaced apart RF frequency ranges in response to the straight portion being electrically excited through a fourth RF feed; another conductive neutralization line that connects the third and fourth radiating elements; and an interconnection conductive neutralization line that connects the conductive neutralization line to the other conductive neutralization line to at least partially cancel RF transmission coupling between the first, second, third, and fourth radiating elements, wherein the straight portions of the first, second, third, and fourth radiating elements lie in a plane that is perpendicular to another plane in which the serpentine portions of the first, second, third, and fourth radiating elements lie.
