Abstract

An integrated repeater is provided that places a donor antenna and a server antenna proximate to null-field points from the server antenna and the donor antenna, respectively, thereby increasing the isolation level between the donor antenna and the server antenna.

Claims

1. An integrated repeater comprising:

a repeater housing;

a donor antenna within the repeater housing, the donor antenna being configured to transmit and/or receive a wireless signal from a base station, the donor antenna emitting a transmission field having one or more null-field points; and

,

a server antenna within the repeater housing and physically separated from the donor antenna, the server antenna being configured to transmit and/or receive a wireless signal from one or more wireless devices, the server antenna being disposed proximate to a location of at least one of the one or more null-field points of the transmission field from the donor antenna for signal isolation between the server antenna and the donor antenna.

2. The integrated repeater as in claim 1, further comprising:

a plurality of donor antennas, within the repeater housing, the donor antennas emitting one or more transmission fields that have a plurality of null-field points within the repeater housing, and;

a plurality of server antennas, within the repeater housing, where individual ones of the plurality of server antennas are disposed proximate to individual ones of the plurality of null-field points within the repeater housing.

3. The integrated repeater as in claim 1, wherein the donor antenna is a dipole antenna.

4. The integrated repeater as in claim 1, wherein the server antenna is a dipole antenna.

5. The integrated repeater as in claim 1, wherein the donor antenna is a multiband antenna.

6. The integrated repeater as in claim 1, wherein the server antenna is a multiband antenna.

7. The integrated repeater as in claim 1, wherein at least one of the one or more null-field points of the signals emitted from the donor antenna and/or the server antenna are aligned with the repeater housing.

8. The integrated repeater as in claim 1, wherein the signals transmitted by the donor antenna and/or the server antenna are orthogonally polarized.

9. The integrated repeater as in claim 8, wherein the orthogonally polarized signals transmitted by the donor antenna are orthogonal to the orthogonally polarized signals transmitted by the server antenna.

10. A method of configuring an integrated repeater, the method comprising:

providing a donor antenna configured to transmit and/or receive a wireless signal from a base station, the donor antenna emitting a signal having one or more null-field points;

providing a server antenna configured to transmit and/or receive a wireless signal from one or more wireless devices, the server antenna emitting a signal having one or more null-field points;

determining the position of at least one of the one or more null-field points of the signal emitted from the donor antenna;

determining the position of at least one of the one or more null-field points of the signal emitted from the server antenna;

positioning the donor antenna proximate to at least one of the one or more null-field points of the signal emitted from the server antenna; and

,

positioning the server antenna proximate to at least one of the one or more null-field points of the signal emitted from the donor antenna.

11. The method as in claim 10, further comprising:

determining the dimensions of a repeater housing based on a requirement that at least one of the positions of the one or more null-field points of the signal emitted by the donor antenna and at least one of the positions of the one or more null-field points of the signal emitted by the server antenna are within the repeater housing when the donor antenna and the server antenna are disposed in the repeater housing.

12. The method as in claim 10, further comprising:

providing a plurality of donor antennas that emit one or more transmission fields having a plurality of null-field points within the repeater housing, and;

providing a plurality of server antennas where individual ones of the plurality of server antennas are disposed proximate to individual ones of the plurality of null-field points.

13. The method as in claim 10, wherein the donor antenna is a dipole antenna.

14. The method as in claim 10, wherein the server antenna is a dipole antenna.

15. The method as in claim 10, wherein the donor antenna is a multiband antenna.

16. The method as in claim 10, wherein the server antenna is a multiband antenna.

17. The method as in claim 10, wherein the dimensions of the repeater housing are determined based on having at least one of the one or more null-field points of the signals emitted from the donor antenna and/or the server antenna being aligned with the repeater housing.

18. The method as in claim 10, further comprising:

orthogonally polarizing the signals transmitted by the donor antenna and/or the server antenna.

19. The method as in claim 18, further comprising:

selecting a plane for the orthogonally polarized signals emitted by the server antenna such that the plane of the orthogonally polarized signals emitted by the server antenna is orthogonal to the plane for the orthogonally polarized signals emitted by the donor antenna.
