WIRELESS DISPLAY TAG (WDT) USING ACTIVE AND BACKSCATTER TRANSCEIVERS |
摘要 |
<p>A method for minimizing power consumption in a wireless device which utilizes backscatter transmission in half-duplex mode, wherein a switching device is interposed between an antenna and a transmitter-receiver, and the switching device is capable of causing the antenna load impedance characteristic to be either a short, a value which substantially matches the antenna impedance, or an open, depending on the portion of the half-duplex mode.</p> |
