Abstract :
This paper presents a low profile planar inverted-F antenna (PIFA) for the sensing tag of UHF RFID applications. The proposed antenna that is optimized by using the multi-slotted PIFA in order to overcome the shortcoming of a narrow bandwidth of a typical PIFA can be increased of 9.2%. The |S11| of the simulated and measured results can be operated in the UHF RFID system in Thailand, which covers the frequency bands from 920 to 925 MHz. Furthermore, the radiation pattern is omnidirectional at 922.5 MHz. Therefore, slotted PIFA can be employed with a UHF RFID sensing tag.
