1. An antenna system comprising:
a flexible and thin polyethylene terephthalate (PET) substrate stack having a length;
a printed circuit board (PCB) comprising one or more Leaky-Wave Antenna (LWA) structures on the PET substrate stack, wherein the one or more LWA structures have a bent-stub folded LWA configuration with longitudinal asymmetry and transverse asymmetry for a broadside frequency;
wherein the bent-stub folded LWA configuration comprises a plurality of conductively unit cells having a unit cell period, wherein 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.
