Millimeter wave (mmWave) Multi Beam Foldable Antenna Array with Tilted Beam holds immense potential for reducing atmospheric absorption, multi-path effects that hinder signal quality at these frequencies, and compact satellite deployment scenarios. However, conventional designs operate in lower millimeter wave spectrum, have complex geometries, don't utilize low-cost air-filled SIW technology (AFSIW), suffer from poor bandwidth, and exhibit poor gain, low scanning coverage, poor pattern re-configurability, don't have tilted and Multiple beams. To address these concerns, an AFSIW Multibeam Foldable Antenna Array with a tilted beam is proposed for the first time based on a Rigid Flex Substrate. The design exhibits a large bandwidth over the entire V-Band, a superior gain of 15.51 dBi, a large scanning coverage, low cost, and superior radiation pattern reconfigurability with a tilted beam. This array finds application in urban-air-mobility (UAM), and satellite communication systems, where mitigating multi-path effects is crucial for enhancing signal quality, and compact deployment is essential. State-of-the-art performance is observed when the work is compared to reported advances in the literature. In conclusion, the work addresses a critical gap and paves the way for cost-effective, high-performance solutions for mmWave communication.
