Microstrip patch antenna fed by inset microstrip line for Radio Frequency Identification (RFID)

This paper presents a design of rectangular microstrip patch antenna using inset line feeding through Radio Frequency Identification (RFID) for physical objects identification. According to related directions of the Director General of Post and Telecommunication in Indonesia, the research has been done with operating frequency antenna of 0.92 GHz. The proposed antenna has characterized as follows, return loss of − 23.06 dB with VSWR 1.155, impedance bandwidth 22.4 MHz or 2.42%, gain 5.76 dB and 40° Half Power Beamwidth of radiation pattern.
