【 摘 要 】

Radio detection and ranging (radar) is a system that can be used to detect and map an object by using electromagnetic waves and the echoes. Radar technology is a system that can help state institutions and apparatus in mastering and securing a country. One of the most important components in a radar is an antenna. The function of antenna is to transmit and receive the signals that will detect the presence of objects around the radar. The antenna commonly used in a radar usually has the high gain, and one of the techniques to enhance the antenna gain is using an antenna array. An antenna array has an important part that is the power divider. In this paper, we will discuss regarding the 1:12 power divider for ground surveillance radar at C-band frequency. We use CST Studio Suite to design and simulate the power divider. In this design and simulation, we use FR-4 with a dielectric constant of 4.5, and the thickness is 1.6 as a substrate. According to the simulation results, it can be seen that this power divider has the bandwidth 200 MHz with the center frequency 5 GHz, VSWR is less than 1.5, and all the output ports are in phase.
