Experimental Verification Directly and Indirectly Light Emitting Diode Integrated with Patch Antenna

This paper presents the design of Rectangular Patch Antenna integrated with Surface Mount Device (SMD) Light Emitting Diode (LED) operating at 2.45 GHz for W-fi application. The main objective of this work is to verify experimentally the direct and indirect integration of patch antenna integration with LED. The antenna was designed and optimized using Computer Simulation Technology (CST) software and fabricated on a Rogers5880 material with thickness of 1.57mm and dielectric constant of 2.2. The LED was integrated with the radiating patch in parallel connection. Experimental investigation was done using Vector Network Analyzer (VNA) to verify the frequency response, return loss, and VSWR of the designed antenna. Both simulation and experimental results were then compared and analyzed. The results verified that the design of the patch antenna can operate at 2.4GHz and it works well as an illumination. The antennas are reasonably well matched at their expected resonance frequency.
