Design of Micro-Machined Frequency Reconfigurable Cascaded Sierpinski Gasket Fractal Antenna using RF-MEMS Switches
In this article, a multiband high gain frequency reconfigurable cascaded Sierpinski gasket fractal antenna (CSGFA) is proposed. The final iteration of the proposed design has been simulated on the high index silicon substrate with relative permittivity of 11.9 and height of ${\mathrm {675}}\mu{\mathrm {m}}$ with the utilization of micro-machining mechanism. Finally, the proposed iteration of the design is made frequency reconfigurable with the incorporation of shunt capacitive micro-electro-mechanical switch (MEMS). The final design shows significant shift in the operating frequencies with acceptable gain around 10 dBi along with the compatibility of the design with monolithic microwave integrated circuits (MMICs).
