A pattern-reconfigurable flexible textile antenna covering the 2.45-GHz industrial, scientific, and medical (ISM) band is presented. The design utilizes RF-switch integrated circuits (ICs) packaged ...

Reconfigurable antenna ensures flexibility design, once it presents frequency agile and makes use of software defined and cognitive radios to cope with extendable and reconfigurable multiservice, ...

Using heat-activated nitinol metal, researchers have devised a reversible, shape-shifting, conical spiral antenna that needs no discrete external actuator. How a special nitinol compound and 3D ...

This letter proposes a broadband reconfigurable antenna capable of forming single and dual beam radiation, with switchable polarization states. The antenna consists of a reconfigurable power divider ...

Researchers from the UK and Ireland are developing a low loss active reconfigurable intelligent surface (RIS) for the next generation of indoor 6G antennas. 6G will include high frequency millimetre ...

This paper introduces a novel reconfigurable superstrate using a band-stop frequency selective surface (FSS) based on four arms star geometry. The proposed reconfigurable superstrate is applied to a ...

These findings were published in IEEE Transactions on Antennas and Propagation on June 27, 2024. To create the model, the research team focused on the fact that the mutual coupling between arbitrary ...

We propose an unsupervised beamforming neural network (BNN) to optimize transmit beamforming in downlink multiple input single output (MISO) channels. Our proposed BNN utilizes only channel ...

This has set the stage for what’s next. The goal is to radically upgrade the frequencies on the reconfigurable designs with the addition of ultra-wideband systems. It’s like giving the antennas better ...
