Summary:
This paper presents a circularly polarized microstrip antenna which consists of slots seriesfed by a microstrip line left open-circuited for RFID shelf applications in the UHF band. A circular polarization of the antenna is realized by a pair of orthogonal slots and a distance between the slots in which the distance is adjusted to excite each slot with two orthogonal electric-field components in phase quadrature.
