roducing compact devices for space technology. Transparent antennas are seen as the solution to this problem. With the presence of a transparent antenna, it can save antenna installation space as its transparency properties allow it to be integrated with solar technology. However, the use of transparent material on the antenna causes the antenna gain to be low due to the low conductivity of the material. When a low conductivity material is used it also causes the antenna efficiency to decrease. Therefore, modifications to the antenna design are needed to overcome such problems. This study aims to design a transparent antenna that can operate on Ku-band. The aim of this study is to identify the effect of transparent materials on conductivity, design a transparent antenna with an efficiency as low as 85% and design a grid array antenna to increase gain. The material verification test is carried out by making a comparison of the material in the antenna design simulation that works on Ku-band. The transparent antenna material selected is Indium Tin Oxide (ITO). Then, the design of the grid array antenna is carried out to increase the antenna gain hence for high efficiency. In this research, 8 loops grid array antennas increase the gain by 52% compared to reference antennas. The antenna meets performance requirements and can be integrated with solar panels to efficiently harness sunlight for electricity generation, while effectively transmitting and receiving wireless signals.
