Analysis of Corner Truncated Rectangular Microstrip Patch Antenna for IoT Applications

A miniaturized, rectangular, corner truncated microstrip patch antenna with FR4 substrate is proposed and simulated for the wearable sensor device IoT applications. The major challenges for developing any device for the healthcare system are sensor-feeding network and active worked element on the same base. The proposed antenna is feed by the microstrip patch line with the 50 Ω impedance. The upcoming resonance frequency is in the range of the ISM region or Wi-Fi technology. The resonating frequency of antenna is 2.44 GHz with the operating bandwidth of the device which is 2.41–2.47 GHz. Rectangle and circular shape slots are inserted in the design for enhancing the current path and direction of the electrical path. The simulated gain of antenna is 5.33 dB with the directivity of 4.76 dB. Small size and high performance are very desirable for the antenna design for the Internet of things (IoT) applications. The simulated result shows that it can be used for the IoT wearable sensor design units.
