CC2531 pcb design using two layers.

• Designed my own antenna using Ansoft HFSS software to simulate impedance matching in 2.4Ghz. • Exported 3D model and implemented the exact dimensions in Altium Designer. • Made and tested three designs, two proposed by TI and one mine, and obtained excellent results on efficiency. • Implemented a complete ZigBee sensor system using the ultra-low cost modules developed.
