  Internet of Things (IoT)-based applications must be integrated with wireless
communication technologies for this make application data easily accessible.
The wireless communication system is a crucial component of IoT infrastructure,
serving as a bridge for bidirectional connection for data gathering and control
message delivery. In this article, a modified meander form microstrip patch
antenna for IoT applications in 2.4 GHz ISM (Industrial, Scientific, and
Medical) band is suggested.The suggested antenna has a gain of up to 4.01 dBi
and an efficiency of up to 90% directivity up to 7.14. Theperformance after
simulation of this antenna that is combined with a 2.4GHz radio frequency
module and IoT sensors. Having small size and high fractional bandwidth which
gives a good performance in IoT application. The patch's length width is 30.2
mm, and its length 47mm at a resonance frequency of 2.4 GHz is 38 mm, with a
feeding offset position of 6 mm. The substrate has a height of 1.5 mm that
appropriate for short-range IoT applications.
