The long-wire dipole antenna is effective for low-frequency systems. Adding LC traps makes a single-band dipole antenna into ...

Abstract: A magnetic Yagi-Uda antenna applying higher order mode in millimeter-wave ... It can achieve anendfiregain of 8–11 dBi within 24–26 GHz with –10 dB impedance band covering an even wider ...

Abstract: The solution of a problem of current distribution in Yagi-Uda antenna with impedance vibrators is represented. The influence of surface impedance of the vibrators on electrodynamical ...

Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is ...

Do they reflect radio waves as well as they reflect heat? As it turns out, yes they do. Any antenna system that’s more than a simple radiator relies on using conductive components as reflectors.

These scales have sensors underneath your feet that use bioelectrical impedance. Bioelectrical impedance uses a weak electrical current to measure the amount of resistance from body fat.

Typhoon Yagi has grown into a super typhoon on Wednesday night and has a high probability of making landfall on the Leizhou Peninsula in Guangdong province, on early Friday morning, said Guangdong ...

In the presence of constriction, the contribution from the non-ideal electrode/solid electrolyte interface to the impedance spectrum may exhibit two signals that cannot be explained when the porous ...
