Patent ID: 8193988

Claim:
An antenna for wireless communication operating in transmission and reception comprising at least two omnidirectional radiating elements with a first radiating element operating in reception according to a first direction of polarization and a second radiating element operating in transmission according to a second direction of polarization, wherein the first and second radiating elements are realized next to each other on a same end of a same surface of a first substrate and radiate in the plane of the said first substrate in the same direction, wherein a first antenna system having the antenna operates with a second identical antenna system having the antenna and being oriented in parallel or at 90° in relation to the first antenna system, said first and second radiating elements being oriented so that the first radiating element of the antenna of the first antenna system co-operates with the second radiating element of the antenna of the second identical operating system and the second radiating element of the antenna of the first antenna system co-operates with the first radiating element of the antenna of the second identical antenna system such that the polarization directions used in reception and in emission in two geometrically distinct configurations of said antennae of the first and second antenna systems being conserved.
