dc.description.abstractIn the modern world there is an abundance of unused, free ambient energy, which includes energy that is dispersed from wi-fi and internet usage. Harvesting this energy is of importance, as it can provide charge to self-sustainable, low-power application such as IoT devices. In this paper, angle-incensitive triple-band meta-material absorber was designed for resonant frequencies at 2.45GHz, 5GHz, 6GHz with an average absorption efficiency of 80%, 95% and 99% for the angle of incidence θ from 0° to 60° respectively. The simulation was done in CST studio suite, and the simulated absorber shows good absorption qualities. Implemented design was a 9 by 9 unit cell metamaterial grid de- ployed using RO4350B substrate and it showed some agreement with the simulations. Moreover, the design showed a better absorption qualities, covering a wider frequencies range than expected. Experimental absorption is perfect over the shifted frequency bands.en_US
