Abstract
An antenna loop structure applicable to a digitizer tablet is capable of reducing effect of electromagnetic interference (EMI) by aggregating a plurality of antenna loops, wherein each antenna loop further comprises a plurality of -shaped segmental antennas, and each pair of immediate neighboring segmental antennas is phase-inverted to each other for counteracting against external EMI.
