Abstract
An integrated K-port antenna where K is an integer equal to 2 or greater and where the antenna is sufficiently small that it can be enclosed by K−1 overlapping spheres each having a diameter of λ/2 where λ is equal to c/f and f represents an operating frequency of the antenna.
Claims25
An integrated K-port antenna where K is an integer equal to 2 or greater, where ports of the antenna have a radiation pattern determined by the shape of the antenna and the positioning of the K-ports relative to each other, and at least 2 of the ports are arranged to transmit and receive independent signals at a common frequency, and further wherein the positioning of the ports is such that the antenna can be enclosed by K-1 overlapping spheres each having a maximum diameter of λ/2, where λ is equal to c/f and f represents an operating frequency of the antenna.
A wireless communication device comprising:
- an integrated K-port antenna where K is an integer equal to 2 or greater, where ports of the antenna have a radiation pattern determined by the shape of the antenna and the positioning of the K ports relative to each other, and at least 2 of the ports are arranged to transmit and receive independent signals at a common operating frequency, and further wherein the positioning of the ports is such that the antenna can be enclosed by K-1 overlapping spheres each having a maximum diameter of λ/2, where λ is equal to c/f and f represents an operating frequency of the antenna;
- and
- at least two radio transceivers, connected to ports of the antenna, where the radio transceivers can transmit and/or receive at least two independent signals at the common operating frequency.
A method of designing an integrated K-port antenna comprising the steps of:
- providing a structure for the K-port antenna;
- determining a resulting radiation pattern for each of the ports;
- and
- modifying the shape of the antenna and the positioning of the K-ports relative to each other such that each of the ports provides a radiation pattern having a main lobe pointing in a different direction and arranging for at least two of the K-ports to be operable to transmit and receive independent signals at a common operating frequency.
