RESEARCHERS DEVELOP INTERFERENCE-RESISTING ANTENNA

摘要

One of the fundamental properties of antennas is reciprocity, or their ability to transmit and receive radio signals with the same efficiency. That natural symmetry is not always an advantage, since it makes antennas more susceptible to noise and interference as they get better at handling radio waves. Now, researchers from the University of Texas at Austin have developed an antenna not bound by the same property. This "non-reciprocal" antenna can independently control signals entering and exiting the antenna more efficiently, and without the need for other electrical components to keep out noise.
