DOIAbstract
In this research, the design, simulation, and fabrication of the first ever 3D metal printed Sierpinski gasket antenna, with multiple resonance characteristics is reported. The antenna is fabricated from Titanium alloy Ti-6Al-4V, using the Direct Metal Laser Sintering (DMLS) technique. Mechanical considerations like Rumsey's principle and the support structures required for overhanging 3D printed structures have also been studied in detail and discussed. The validity of the DMLS technique for manufacturing a complex shaped (fractal) antenna is assessed, by comparing CST (Computer Simulation Technology) simulation results with the measured data.</p
