Problem statement. Fan-shaped antenna systems can increase the noise immunity of the communication channel, which is especially in demand when used with highly mobile robotic systems. Antennas on an air substrate play a special place in solving such problems.

Goal. Consider the design of an antenna based on an air substrate with an isolated power supply layer to improve the antenna characteristics. Results. The antenna was modeled and a model was made. The obtained characteristics confirm the effectiveness of the proposed solution. Practical significance. The use of an isolated power line made it possible to reduce the size of the antenna, as well as increase the level of the radiation pattern. The results show that the developed antenna allows you to form a fan-shaped radiation pattern, which allows for noise-proof, highly efficient communication with mobile robotic systems, such as autonomous robots or unmanned aerial vehicles.
