Parametric Study of Integrated Stacked Microstrip Antenna with Light Emitting Diode (LED) for Wi-Fi Application

Abstract

In this paper the parametric study of integrated rectangular stacked microstrip antenna with Light Emitting Diode (LED) for Wi-Fi application is presented. There are two objectives in this design: one is the analysis of when the LED placed at difference layer from the radiating patch, another one analysis is by looking at the electrical connection of 18 LEDs in series, parallel and a combination of series and parallel. The antenna was simulated design and optimized at 2.45 GHz using Computer Simulation Technology (CST) with permittivity, εr = 4.5 and thickness, h = 1.6mm on FR4 substrate. The LED placed on the top substrate as the parasitic element. The radiating patch is placed at the second layer of substrate and aperture coupled feeding network was used in this design. The antennas are reasonable well matched at their corresponding frequency of operations. The simulation results have shown that the antenna works well.
