In this paper, a novel broadband high-selectivity stacked filtering antenna with multiple radiation nulls is proposed. The antenna consists of a short-circuited stepped impedance feeding line and two ...

New passive metasurface design filters wireless signals without power, offering a breakthrough for Iot and next-gen communication systems.

Abstract: Electrically large modulated metasurface antennas (MMAs) possess advantages of simple feeding and absence of beam forming network, while achieving a high radiation gain. However, they suffer ...

The design incorporates metasurface panels with internally coupled ... While the current prototype uses simplified antenna designs and commercial diode products, the team believes performance ...

Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

NEW DELHI: Ericsson has tied up with Indian IT hardware and telecom gear maker VVDN Technologies for localising 100% of passive antenna system production by June 2025, as the Swedish telecom gear ...
