Objective: To design a frequency reconfigurable fractal antenna for satellite applications. Methods: Using fractal geometries, a novel structure has been developed to operate the antenna at X (8-12 GHz), Ku (12-18 GHz) and Ka (26.5-40 GHz) bands. Findings: Frequency reconfigurable antennas are generally equipped with PIN diodes or MEMS switches etc., by controlling the switch conditions (ON or OFF) the proposed antenna can be operated either at X or Ku or Ka band. Various parameters of the antenna like reflection coefficient, gain, VSWR, radiation pattern, bandwidth were also determined. Application: This proposed antenna is compact in size and good impedance matching is achieved compared to existing antennas and hence it is very suitable to satellite applications.
