SELF-RECONFIGURABLE ANTENNA
First Claim
1. A passive, self-reconfigurable antenna device comprising:
- at least one antenna element configured to receive a modulated or an unmodulated wireless signal;
a power harvester configured to obtain power from the modulated or unmodulated wireless signal; and
a first switch coupled to the power harvester and powered by the obtained power from the power harvester, the first switch being configured to operate automatically when receiving the obtained power without requiring the receipt of control information;
wherein the first switch automatically operates according to a predetermined pattern when receiving the obtained power to modulate the antenna element.

Abstract
A passive, self-reconfigurable antenna device, components of a corresponding wireless network, and methods pertaining to operations and controls of the antenna device are provided. The antenna device can include at least one antenna element configured to receive a modulated or unmodulated wireless signal, a power harvester configured to obtain power from the modulated or unmodulated wireless signal, and a first switch coupled to the power harvester and powered by the obtained power from the power harvester. The first switch can be configured to operate automatically when receiving the obtained power without requiring the receipt of control information. Further, the first switch can be configured to automatically operate according to one or more predetermined operating patterns when receiving the obtained power to modulate the corresponding antenna element. This way, antenna operating frequency, or radiation pattern or polarization states can be reconfigured.
