Towards a new antenna paradigm with waveform-selective metasurfaces

An international research team has developed reconfigurable antennas using artificially engineered structures called “metasurfaces” that can help solve the issue of limited frequency resources for wireless communications. These antennas provide variable response to waves of the same frequency but different pulse width. Thus, it provides a new degree of freedom to these antennas, making for

Device transmits radio waves with almost no power—without violating the laws of physics

This experimental setup shows an ultra-low-power wireless communications device that could one day be used in tiny remote sensors. Credit: Zerina Kapetanovic, CC BY-ND A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that

New and improved multi-band operational receiver for 5G radio communication

Graphical abstract. Credit: IEEE Journal of Solid-State Circuits (2022). DOI: 10.1109/JSSC.2022.3214118 An ultra-wide-band receiver based on a harmonic selection technique to improve the operational bandwidth of 5G networks has been developed by Tokyo Tech researchers in a new study. Fifth generation (5G) mobile networks are now being used worldwide with frequencies of over 100 Hz.
