This contribution proposes a planar layout which combines the tuning agility of the shaped-slot based tags and the decoupling
from the body achieved by grounded antennas. The basic configuration comprises a folded patch sourced by an embedded
H-slot whose main features are: on-body gain higher than previous examples in [10] and comparable with that of tags over
metal, approximately constant radiation performances regardless of the different body positions, reduced sizes and the predisposition to host passive sensors.
