Review Paper for Design and Simulation of a Patch antenna by using HFSS IJTSRD
In modern times needs for Broadband application has increased. In resent year many work done by design of antenna system. T-shape slot antenna has nearly omnidirectional radiation patter for all operating bands and gain variation of the range in each of the bands can be less than 3dBi. The maximum impedance bandwidth reaching about 121% […]
Visible Light Communication for Visually Impaired People using Sustainable LEDs IJTSRD
We developed navigation system prototype for the visually impaired using LED lights. Where LED lights emit visible light with location data and a smartphone or blind person’s stick with a visible light receiver receives the data. The controller with receiver calculates the optimal path to a designation and speaks to the visually impaired through a […]
