Wideband Monocone with Integrated Coaxial Bandpass Filter for UAV Applications

Wideband monocone antenna integrated with a curved coaxial bandpass filter and operating from around 1 to 5.5 GHz is discussed. The RF ground is modified to represent a conical skirt. To reduce the volume, the bandpass filter recta-coaxial line used for feeding the antenna is curved within the volume of the grounding. The proposed RF front-end is designed for monolithic fabrication using additive techniques and seamless integration at the back end of unmanned aerial vehicles.
