Özet
In this paper, a broadband and high gain microstrip patch antenna was designed with a microstrip feeding technique to operate in the electromagnetic spectrum in the X-band in the frequency range of 7.2 - 8.4 GHz, which is allocated for use in military satellite communication. In this design, Rogers RT / duroid 5880 material with a thickness of 3.175mm, dielectric coefficient of 2.2 and tangent loss (tan ?) of 0.0009 was selected and simulated on the HFSS program. Since the antenna sizes calculated by numerical methods are difficult to adjust to operate in appropriate frequency ranges, the dimensions of the antenna designed using the genetic algorithm, which is a part of artificial intelligence optimization algorithms, have been optimized to work in the desired frequency ranges. According to the designed antenna simulation results, it operates in the frequency ranges of 7.06 - 8.41 GHz and the designed antenna has a bandwidth of approximately 1.35 GHz = 17.25%. At 7.825 GHz center frequency, the antenna's gain is approximately 7.2 dB. In order to increase the bandwidth of the designed antenna, a second antenna design was realized by optimizing the dimensions of the antenna covered with copper and microstrip feeding. The second antenna designed as a result of the changes made on the antenna operates in the frequency ranges of 6.74 - 9.69 GHz and the designed antenna has a bandwidth of approximately 2.95 GHz = 37.7%. At the central frequency of 7.825 GHz, the antenna's gain is approximately 6.63 dB.
