Zero-order energy smart antenna and repeater
View Patent ↗The invention is a new device that will improve the radio link quality for low power wireless devices. An example application is for low power, miniaturized wireless sensor nodes that are statically deployed in a slowly varying environment or that have limited mobility. The device is a reconfigurable antenna that is novel in that it operates with very low (zero-order) energy in contrast to existing system that required both significant computational and DC power.
1. An adaptive antenna apparatus, comprising:
an array antenna including N (N being a natural number) antenna elements configured in an electronically-steered network;
a sampling module;
an adaptive beam control circuit;
said electronically-steered network including reverse-based diodes; and
a configuration module, a correction module, and said sampling module consuming about zero DC energy.
2. The antenna of claim 1 , further comprising: said configuration module adapted to determine optimum signal reception.
