Abstract
A radio-frequency identification (RFID) antenna, per an implementation, includes a substrate, a metalized pattern, one or more slots, a ground plane, a shorting strip, and one or more feed lines. The metalized pattern has microstrip segments and a lateral microstrip. The slot(s) is situated between the microstrip segments. The ground plane extends from the substrate via the shorting strip. The feed line(s) resides on a surface of the substrate. In a slot mode of use of the RFID antenna, an electromagnetic field radiates from the slot. In a patch mode of use of the RFID antenna, an electromagnetic field radiates adjacent ends of the metalized pattern.
