Development of Rectangular Loop Microstrip Antenna Integrated with Light Emitting Diode (LED) for Wi-Fi Application

Abstract:

This paper presents the development of a rectangular loop microstrip patch antenna integrated with Light Emitting Diode (LED) for Wifi application. The objective to integrate with LED is to have dual applications in a device which illumination and also wireless communication. The antenna was designed at a frequency of 2.4 GHz and Computer Simulation Technology (CST) was used to optimized the position of LED within the rectangular loop antenna. The performances of the antenna in terms of return loss, gain and radiation pattern was verified through simulation by using Microwave Studio in CST. The antenna was fabricated on FR4 substrate with permittivity, ε_{r =} 4.5 and thickness, h = 1.6mm. The LED integrated within the patch was conducted parallel and was measured by Vector Network Analyser (VNA) to demonstrate the capacity and potential of the antenna. The antennas are reasonably well matched at their corresponding frequency of operations between simulation and experiment.
