Abstract: Single negative metamaterial designed in MIMO antenna is suitable for portable applications. Metamaterials reduce the coupling at a separation distance of 0.18-wavelength for the MIMO system ...

Abstract: The traditional approach of radio frequency electromagnetic field exposure compliance assessment is highly conservative when applied to radio base station antennas implementing dynamic ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, it’ll take a couple ...
