Design of C-Band Microstrip Fractal Antenna Combined with Pyramidal Horn

The current delivery method in multilevel array distribution is used to create a fractal microstrip antenna in the shape of a stacked box. The fractal antenna was chosen because it has a large antenna working bandwidth due to the repeating of the physical form of the fractal itself, giving it the appearance of a combination of many antennas that may be merged into a single fractal antenna. The proposed fractal microstrip antenna has a working bandwidth of 2.62 GHz to 5.67 GHz and a working range of 3.05 GHz. This fractal microstrip antenna is combined with a high directivity pyramidal horn to boost the antenna gain. The proposed feed antenna combines a fractal microstrip antenna and a pyramidal horn. The combination of these two antennas can produce a gain of 9.18 dB. The simulation was extended by combining the proposed antenna with a 2.4-meter-diameter parabolic reflector to meet the criteria for a ground station receiving antenna on the C-band frequency. The gain produced by this combination is 30.8 dB. The simulation result for return loss, E and H plane radiation pattern, and antenna gain, show that this antenna configuration can be used for Himawari-9 data reception.
