[GENERAL] How does a folded pcb antenna performs? Is there a reduction in gain versus a straight antenna ?

A folded pcb antenna may perform as good as sma quarter wave antenna. The antenna performance is mostly depending on the ground plane. The main difference is that a folded antenna will have different radiation pattern, and not have the 360 deg direction as a quarter wave standing on a solid ground plane.
