Conformal and flexible leaky-wave antenna arrays with reduced mutual couplings

Abstract

Methods and systems are disclosed for an antenna system capable of optimal broadside radiation. In certain embodiments, a system may include a flexible and thin polyethylene terephthalate (PET) substrate stack having a predetermined length. The system may include a printed circuit board (PCB) fabrication of one or more Leaky-Wave Antenna (LWA) structures on the PET substrate stack. The one or more LWA structures have a bent-stub folded LWA configuration have longitudinal asymmetry and transverse asymmetry for a broadside frequency. The bent-stub folded LWA configuration comprises a plurality of conductively unit cells having a unit cell period. Each unit cell of the plurality of conductively unit cells has a folded main feed-line and a bent stub pair with two angularly bent radiating stubs. Embodiments are structured to increase radiation per-unit length and suppress open stopband (OSB).
