Self-reconfigurable antenna
First Claim
1. A passive, self-configurable antenna device, comprising:
- at least one antenna element, comprising a first antenna and a second antenna, the first antenna configured to receive a modulated or an unmodulated wireless signal;
a power harvester configured to obtain power from the modulated or the 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 receipt of control information;
wherein the first switch connects the first antenna and the second antenna when turned on, and wherein the first switch automatically operates according to a predetermined pattern when receiving the obtained power to modulate the at least one antenna element, and wherein the at least one antenna element radiates resonantly when the first switch is turned on.

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.

14. A method for redirecting an antenna radiation pattern of an antenna device, the method comprising:
-
receiving a modulated or unmodulated wireless signal; harvesting power from the modulated or the unmodulated wireless signal; and in response to harvesting power from the modulated or the unmodulated wireless signal, automatically operating a first switch without requiring receipt of control information; wherein automatically operating the first switch includes connecting a first antenna to a second antenna when turned on, wherein the second antenna redirects the antenna radiation pattern using at least one of a plurality of switchable elements. - View Dependent Claims (15, 16, 17, 18, 19, 20)
