Abstract

The disclosure concerns an antenna subsystem that can be used in various repeater systems to optimize gain of the repeater by increasing isolation between donor and server antennas, wherein at least one of the donor and server antennas is an active multi-mode antenna.

Claims

1. An antenna system for optimizing gain of a repeater, comprising:

a donor antenna sub-system that accepts an incoming signal;

a server antenna sub-system configured to relay an optimized version of the incoming signal;

a processor configured to determine an optimal configuration for the antenna system for generating the optimized version of the incoming signal, the optimal configuration being based on an optimal value of a cost function of operating the donor antenna sub-system and/or the server antenna sub-system in each of one or more operational configurations, the cost function being based on one or more operational inputs;

characterized in that;

the donor antenna sub-system comprising a multi-mode antenna adapted for configuration in one of a plurality of possible antenna modes, the multi-mode antenna exhibiting a distinct radiation pattern when configured in each of the antenna modes;

wherein the optimal configuration for the antenna system is achieved by configuring the multi-mode antenna in the one of the plurality of possible modes.

2. The antenna system of claim 1, wherein the server antenna sub-system comprises a second multi-mode antenna adapted for configuration in one of a plurality of possible second antenna modes, the second multi-mode antenna exhibiting a distinct radiation pattern when configured in each of the second antenna modes;

wherein the optimal configuration for the antenna system is achieved by configuring a respective mode of each of the multi-mode antennas.

3. An antenna system for optimizing gain of a repeater, comprising:

a donor antenna sub-system that accepts an incoming signal;

a server antenna sub-system configured to relay an optimized version of the incoming signal;

a processor configured to determine an optimal configuration for the antenna system for generating the optimized version of the incoming signal, the optimal configuration being based on an optimal value of a cost function of operating the donor antenna sub-system and/or the server antenna sub-system in each of one or more operational configurations, the cost function being based on one or more operational inputs;

characterized in that;

the server antenna sub-system comprises a multi-mode antenna adapted for configuration in one of a plurality of possible antenna modes, the multi-mode antenna exhibiting a distinct radiation pattern when configured in each of the antenna modes;

wherein the optimal configuration for the antenna system is achieved by configuring the multi-mode antenna in the one of the plurality of possible modes.

4. The antenna system of claim 3, wherein the donor antenna sub-system comprises a second multi-mode antenna adapted for configuration in one of a plurality of possible second antenna modes, the second multi-mode antenna exhibiting a distinct radiation pattern when configured in each of the second antenna modes;

wherein the optimal configuration for the antenna system is achieved by configuring a respective mode of each of the multi-mode antennas.
