Abstract
A system and method for antenna diversity in a communication system are provided, the system including multiple antennas, including at least one modal antenna, wherein each of the at least one modal antenna has multiple modes corresponding to multiple radiation patterns, and a processor coupled to the multiple antennas and configured to select a mode among the multiple modes to optimize signal quality for each time interval based on a CQI.
Claims21
A communication system, comprising:
- a plurality of antennas, the plurality of antennas including at least one modal antenna, each of the at least one modal antenna including a radiating element positioned above a circuit board forming a volume of the antenna therebetween, and a parasitic element positioned adjacent to the radiating element, wherein each of the at least one modal antenna is configurable about a plurality of distinct modes upon varying a reactance associated with the parasitic element, wherein each of said modes corresponds to one of a plurality of radiation patterns associated with the modal antenna;
- and
- a processor coupled to the plurality of antennas and configured to select a mode among the plurality of modes to optimize signal quality for each time interval based on a channel quality indicator (CQI), the processor further configured to selectably vary the reactance of the parasitic element of each of the at least one modal antenna.
A method for implementing antenna diversity in a communication system, comprising:
- providing a plurality of antennas, the plurality of antennas including at least one modal antenna, each of the at least one modal antenna including a radiating element positioned above a circuit board forming a volume of the antenna therebetween, and a parasitic element positioned adjacent to the radiating element, wherein each of the at least one modal antenna is configurable about a plurality of distinct modes upon varying a reactance associated with the parasitic element, wherein each of said modes corresponds to one of a plurality of radiation patterns associated with the modal antenna;
- and
- selecting a mode among the plurality of modes to optimize signal quality for each time interval based on a channel quality indicator (CQI).
