PROJECT TITLE :

Amorphous Silicon Solar Vivaldi Antenna

ABSTRACT:

An ultrawideband solar Vivaldi antenna is proposed. Cut from amorphous silicon cells, it maintains a peak power at 4.25 V, which overcomes a want for lossy power management elements. The wireless Communications device will yield solar energy or function as a rectenna for twin-supply energy harvesting. The solar Vivaldi performs with 0.5-two.eight dBi gain from zero.ninety five-a pair of.45 GHz , and in rectenna mode, it covers three bands for wireless energy scavenging.
