Integration of antennas into ground, air or water vehicles is a critical task due to the increasing number of RF and microwave systems used for communication, RADAR or ESM. Structural aspects such as mechanical or thermal stability, aerodynamics or outer appearance are of great importance. The performance of the system may not be affected by the influence of the platform or by electromagnetic interaction between different systems. The proposed paper describes the design of a distributed antenna array with large field of view (LFoV) for an additional communication system in C-Band. The specifications require a coverage of 360 deg of angle in azimuth and more than 60 deg of angle in elevation at high levels of directivity. While traditional antenna systems (e.g. rod or fin type antennas; cylindrical or spherical Radomes) change the outer appearance of the vehicle and can deteriorate the aerodynamic behaviour of the aircraft, it was the aim of a research study to integrate antennas into the interior structure of the aerial vehicle with a minimum of changes to the construction of the system. The paper describes the design of the antennas and presents simulation as well as experimental results of a demonstrator system.
