"researchers screen-printed a flexible quasi-Yagi antenna on a dielectric substrate to show that the device performed well in the millimeter-wave band when bent or folded... will be beneficial for novel 5G antennas and accelerate the implementation of 5G... inks are compatible with roll-to-roll processing, which can help meet the high demand for wearable sensors at low costs... expect fabrication costs to be extremely low, to the extent that the devices will become disposable"
