Abstract

The aircraft's performance, such as the flight time and maneuverability, can be greatly enhanced by using carbon fiber in the composites, which makes these kinds of materials widely used in modern aircraft. The aircraft composites with carbon fiber have different transmission and reflection characteristics compared to the composites with metal, and the radiation pattern of aircraft antennae will be extremely complicated due to the carbon fiber with different types, proportions, growth methods, and thicknesses. However, most of the simulations and designs of aircraft antennas do not take into account the influence of different materials. In this paper, the radiation pattern of an L-band omnidirectional antenna in typical application scenarios is analyzed by simulation and experiment. The results show that the carbon fiber composite has a greater effect on the radiation pattern and the gain of the antenna drops more than to 15dBi in some directions. The results indicated that traditional aircraft antenna design does not consider the effect of different materials, so there is a significant simulation error, and the influence of carbon fiber materials should be considered in the early stage of link design.
