Abstract

A wireless repeater with features that improve the server-donor antenna isolation including multi-purpose server and donor mounting plates that each carry an antenna feed circuit board and associated antenna elements mounted in a back-to-back arrangement with the duplex repeater electronics board sandwiched between the server and donor mounting plates. To improve the server-donor antenna isolation, one or both mounting plates may include corner, side tabs, which may be asymmetric, and raised walls around one or both mounting plates. In addition, the radomes covering the donor antenna and/or the server antennas may carry one or more parasitic conductors, such as a two parasitic strips arranged in parallel lines or for parasitic strips arranged in a square configuration.

Claims

1. A wireless repeater, comprising:

a duplex repeater electronics board;

a donor mounting plate carrying the repeater electronics board one side and a donor antenna feed circuit on an opposing its opposing side;

a server mounting plate carrying the repeater electronics board one side and a server antenna feed circuit on an opposing its opposing side; and

the donor mounting plate, the server mounting plate, and the duplex repeater electronics board affixed to each other to form an integral housing, whereby the donor antenna is configured for orientation in an operable donor direction for exchanging duplex cellular communication signals with one or more base stations, and the server antenna is configured for orientation in an operable server direction for exchanging duplex cellular communication signals with one or more wireless telephone units.

2. The wireless repeater of claim 1, wherein one or both of the server and donor mounting plates comprise walls forming one or more isolation zones substantially enclosing certain portions of the electronic board to reduce the release of electromagnetic energy radiating from these zones of the electronic board.

3. The wireless repeater of claim 1, wherein one or both of the server and donor mounting plates comprise one or more side walls to reduce the release of electromagnetic energy radiating from these zones of the electronic board.

4. The wireless repeater of claim 1, wherein one or both of the server and donor mounting plates comprise one or more corner tabs for reducing the amount of energy radiated by the donor antenna that propagates around the common housing and into the server antenna.

5. The wireless repeater of claim 1, wherein one or both of the server and donor mounting plates comprise one or more asymmetric sets of corner tabs or side tabs for reducing the amount of energy radiated by the donor antenna that propagates around the common housing and into the server antenna.

6. The wireless repeater of claim 1, further comprising:

a user-operable frequency range selector for identifying a selected frequency range;

a display for showing information connoting the selected frequency range; and

wherein the wireless repeater is operable for providing wireless repeater service within the selected frequency range.

7. The wireless repeater of claim 1, further comprising:

a first radome covering the donor antenna;

a second radome covering the server; and

one or more parasitic conductors carried by the first or second radome.

18. The wireless repeater of claim 1, wherein one or both of the server and donor mounting plates comprise walls forming one or more isolation zones substantially enclosing certain portions of the electronic board to reduce the release of electromagnetic energy radiating from these zones of the electronic board.

19. The wireless repeater of claim 1, wherein one or both of the server and donor mounting plates comprise one or more of the following features to reduce the release of electromagnetic energy radiating from these zones of the electronic board:

side walls, corner tabs and side tabs.

20. The wireless repeater of claim 19, one or both of the server and donor mounting plates comprise one or more asymmetric sets of corner tabs or side tabs for reducing the amount of energy radiated by the donor antenna that propagates around the common housing and into the server antenna.

8. A wireless repeater, comprising:

a duplex repeater electronics board;

a donor mounting plate carrying the repeater electronics board one side and a donor-antenna feed circuit on an opposing its opposing side;

a server mounting plate carrying the repeater electronics board one side and a server antenna feed circuit on an opposing its opposing side;

the donor mounting plate, the server mounting plate, and the duplex repeater electronics board affixed to each other to form an integral housing, whereby the donor antenna is configured or orientation in an operable donor direction for exchanging duplex cellular communication signals with one or more base stations, and the server antenna is configured for orientation in an operable server direction for exchanging duplex cellular communication signals with one or more wireless telephone units; and

wherein one or more of the donor mounting plate and the server mounting plate comprise one or more walls forming one or more isolation zones substantially enclosing certain portions of the electronic board to reduce the release of electromagnetic energy radiating from these zones of the electronic board.

9. The wireless repeater of claim 8, wherein one or both of the server and donor mounting plates comprise one or more corner tabs for reducing the amount of energy radiated by the donor antenna that propagates around the common housing and into the server antenna.

10. The wireless repeater of claim 8, wherein one or both of the server and donor mounting plates comprise one or more side tabs for reducing the amount of energy radiated by the donor antenna that propagates around the common housing and into the server antenna.

11. The wireless repeater of claim 8, wherein one or both of the server and donor mounting plates comprise one or more asymmetric sets of corner tabs and side tabs for reducing the amount of energy radiated by the donor antenna that propagates around the common housing and into the server antenna.

12. The wireless repeater of claim 11, further comprising:

a first radome covering the donor antenna;

a second radome covering the server; and

one or more parasitic conductors carried by the first or second radome.

13. The wireless repeater of claim 12, further comprising:

a user-operable frequency range selector for identifying a selected frequency range;

a display for showing information connoting the selected frequency range; and

wherein the wireless repeater is operable for providing wireless repeater service within the selected frequency range.

14. A wireless repeater, comprising:

a duplex repeater electronics board;

a donor antenna;

a server antenna;

a first radome covering the donor antenna;

a second radome covering the server; and

one or more parasitic conductors carried by one or both of first and second radomes.

15. The wireless repeater of claim 14, wherein the first radome and the second radome carry one or more of the parasitic conductors.

16. The wireless repeater of claim 15, wherein the parasitic conductors comprise elongated strips, and the first and second radomes each carry two substantially vertical parasitic strips or four parasitic strips arranged in a square configuration.

17. The wireless repeater of claim 16, further comprising:

a user-operable frequency range selector for identifying a selected frequency range;

a display for showing information connoting the selected frequency range; and

wherein the wireless repeater is operable for providing wireless repeater service within the selected frequency range.
