Abstract
Various adaptive antenna systems are presented in which the structure of the antenna is configured to realize different radiation patterns. Such arrangements can include electrically connecting and disconnecting portions of the antenna structure to determine an arrangement that results in a higher signal strength in an unknown operating environment, such as in a home in which wireless devices that communicate with each other may be placed in varying directions with respect to each other.
Claims20
An adaptive antenna system, comprising:
- an adaptive antenna comprising:
- a first radiating element;
- a second radiating element;
- a switch that electrically connects and disconnects the first radiating element and the second radiating element, wherein a type of antenna of the adaptive antenna varies based on whether the first radiating element is electrically connected with the second radiating element;
- and
- an antenna controller that controls actuation of the switch, wherein a radiation pattern of the adaptive antenna varies at a particular frequency based on the first radiating element and the second radiating element being electrically connected or disconnected via the switch.
3 more elements
An adaptive antenna array, comprising:
- a first antenna;
- a second antenna;
- a first electrical connection from the first antenna to a transceiver;
- a second electrical connection apparatus that connects the second antenna to the transceiver, wherein the second electrical connection apparatus comprises a phase control component;
- and
- an antenna controller that controls a phase of an electrical signal via the phase control component, wherein a radiation pattern of the adaptive antenna array varies at a particular frequency based on a state of the phase control component.
3 more elements
An adaptive antenna system, comprising:
- an adaptive antenna, comprising:
- a first radiating element having a first length, wherein the first length of the first radiating element corresponds to a first harmonic of a frequency;
- a second radiating element having a second length, wherein the second length of the second radiating element corresponds to a second or higher harmonic of the frequency;
- a switch that alternatively connects a transceiver with the first radiating element or the second radiating element, wherein the transceiver transmits or receives at the frequency;
- and
- an antenna controller that controls actuation of the switch between the first radiating element and the second radiating element, wherein a radiation pattern varies at a particular frequency based on whether the first radiating element or the second radiating element is electrically connected with the transceiver via the switch.
