Improved designs for an antenna system that facilitates narrowband and wideband radio frequency (RF) communications in a rotary aircraft are disclosed. The antenna system includes a RF front-end and a RF back-end. The front-end includes multiple RF components structured to transmit or receive RF communications as electromagnetic waves into three-dimensional space. These RF components form parts of at least one of the aircraft's rotor blades. Moreover, some of the RF components are of differing types, thereby causing the rotor blade to include multiple different types of RF components. The back-end, on the other hand, is located at a position other than the rotor blades and is connected with the front-end via the aircraft's rotary hub, which is connected to the rotor blades.
