Abstract

Using this antenna, we can precisely detect minute objects, such as raindrop particles. Utilizing a linear array antenna, we are increasing the system's gain. The X-band radar uses the electromagnetic spectrum and has a frequency range of 8 GHz to 12 GHz. With the proper antenna requirements, X-band radar can be used for maritime radar with ship navigation capabilities as well as weather radar. A microstrip antenna with a unidirectional pattern is necessary for the x-band radar application as a ship navigation instrument. The system is incredibly sensitive to small objects. Miterbends are employed for better impedance matching. The use of miter bends reduces the reflection coefficient. This study limits radiation to up to 8 elements and then includes a method to widen the bandwidth of antennas. Taking into account the lifetime and material restrictions of the antenna design. The finished antenna is 142.40 mm x 42.8 mm in size. According to the measurement results, the antenna is linearly polarized, has a unidirectional pattern, and has the following specifications: fc = 9.496 GHz, S11 = -32.64 dB, VSWR 1.05, bandwidth = 41.9 MHz (9.5159 GHz - 9.4740 GHz), and gain 8.8 dBas. The radar antenna typically has a narrow beam and a high gain.
