Tiny chip antenna fits all the GSM/LTE bands and GPS too

Fractus Antennas of Barcelona has developed a mobile antenna that supports coverage in the frequency bands for 3G, 4G and 5G. Called TRIO mXTEND, the multi-band and multi-port antenna component is reconfigurable by the user. This chip antenna has been designed for mobile operation in three different frequency bands: 698-960MHz, 1710-2690MHz and 3400-3800MHz. Physically the device is small, measuring only 1.0 mm in ...

Updated: Perovskite solar cells that lasts in air

Perovskits solar cells have gone from nothing to 23% efficiency in a decade, but they are fragile in air. Now researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have made perovskite cells that, without protective encapsulation, retain 88% (+/-4%) of their 12.2% starting efficiency after 1,000 hours exposure to air, moisture ...

THz solar antennas instead of solar cells

Rather than splitting an exiton across a p-n junction, why not receive light like radio waves, with an antenna and a diode? That is the thinking behind a project at Georgia Tech, which has produced a class of devices called rectennas. The first optical rectenna was produced in 2015, now the Tech is reporting a ...

Optical modulator has no output offset

Researchers at the University of Pennsylvania have created a an optical second-harmonic generator with no background output – second harmonic output can be varied from zero upwards. It consists of an 8μm long strip of cadmium sulphide with source and drain electrodes (one Ohmic, on Schottky) – see diagram. Incoming light was between 680 and ...
