Investigation on integrated archimedean spiral patch antenna with Light Emitting Diode (LED)

This paper proposed the design of Archimedean Spiral Patch Antenna integrated with Surface Mount Device (SMD) Light Emitting Diode (LED) operating at 2.4GHz for Wireless Local Area Network (WLAN) application. The antenna was designed and optimized using Computer Simulation Technology (CST) software before implemented on a FR-4 material with thickness of 1.6mm and dielectric constant of 4.3. 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 analysed. The results had been 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 corresponding frequency of operations.
