Due to the increase in internet-connected devices in daily life, the compact embedded wireless device becomes necessary to meet multiple frequency-based applications on a common platform. Reconfigurability is a good solution for improving device utility in many technical interfaces. Wireless compatibility between different devices over the Internet reveals the importance of the antenna unit. Internet of Things (IoT) based applications requires integration with wireless communication technologies to obtain application data. In this study, a meander-shaped microstrip patch antenna in the 5.8 GHz band is proposed for use in IoT applications. The dimensions of the antenna are 40 x 15 x 1.6 mm3. The antenna design consists of a full circle, a semicircle, and a meander line. In the antenna design, FR-4 has been used as the substrate material, and copper has been used as a conductor on the upper and lower surfaces. Performance parameters have been investigated in the proposed antenna design. In addition, a parametric study is presented to investigate the flexibility of the antenna. The results show that gain and yield can be improved by adjusting the dimensions of the rectangular ground plane. As a result of the improvements, the terminated antenna, return loss below -20 dB in the 5.8 GHz band, 700 MHz wide operating band, 4.35 dBi realized gain, 5.3 dBi directivity, -0.9188 dB radiation efficiency and -0.9445 dB total efficiency have been obtained. In addition, the proposed antenna also operates in the 4.5 GHz, 7 GHz, and 8.5 GHz bands as multi-band.
