Multiband Antenna Deploying Swastika Slotted Fractal for WLAN Utilities

Abstract

The Swastika slotted fractal antenna is unveiled in this article that exhibits multiband operation that can used for different WLAN applications like Bluetooth and Wi-Fi, The proposed antenna has been designed on substrate of material FR4 with 1.6 mm thickness, 0.02 loss tangent and 4.4 dielectric constant. The simulation is done using IE3D simulator and experimentally verified through Rohde & Schwarz ZVL Vector Network Analyzer. Antenna parameters like S-Parameter (S11), Voltage Standing Wave Ratio (VSWR) and Directivity are investigated. The values of measured S-Parameter (S11) are −26.59 dB, −24.31 dB and −12.39 dB for frequencies 2.45 GHz, 2.77 GHz and 2.99 GHz respectively. The results of designed and fabricated prototype are in good coalescence with each other.
