Continuous Scanning Dielectric Lens Antenna
This work presents a proof of concept for a high-gain, continuously beam-scanning Ka-band antenna, designed for collision avoidance radar. The antenna features a modified dielectric lens to mitigate scanning loss, fabricated using low-cost Polylactic Acid (PLA) through additive manufacturing. A slotted substrate integrated waveguide (SIW) serves as the feed system, meeting compactness requirements. The resulting antenna system combines a cost-effective modified lens with a 6-slot SIW frequency-scanning array and a single transmission channel, enabling frequency scanning over an 80° angular range with a simulated realized gain of around 14 dBi. The final prototype is currently under fabrication process for experimental validation.
