dc.description.abstractHerein, thin films of Nb2O5 are deposited onto semitransparent indium and glass substrates using the sputtering technique. Optical analyses revealed significant improvement in light absorption, displaying a maximum enhancement of 1900% at an incident photon energy of 2.29 eV. The dielectric constant of Nb2O5 is increased by 289% after coating onto indium substrates. In addition it increased the values of terahertz cutoff frequency making the In/Nb2O5 interfaces promising for use as optical band filters adequate for terahertz technology. On the other hand the experimentally designed In/Nb2O5/Ag antennas were tested in the frequency domain of 0.01–1.80 GHz. The antennas exhibited excellent performance across the quad-band range. The four lower bandstop edges of the AC transmission line are centered at 0.67 GHz, 1.19 GHz, 1.42 GHz, and 1.65 GHz. Additionally, the MIM antenna demonstrated a negative capacitance effect beneficial for canceling passive antenna modes, thereby resulting in high transmission rates with minimal power loss.
