Abstract: Abstract EBG-backed circular patch antenna for multiband applications which is unique is proposed in this study which is useful in the development of smart cities. In CST, the planned EBG-backed circular patch antenna is modeled and built for testing. The suggested antenna is 35 mm in length and 35 mm in breadth. The suggested antenna has return losses of − 52.5 dB, − 44 dB, and − 28 dB at resonating frequencies of 4.5 Gigahertz, 5.2 Gigahertz, and 5.6 Gigahertz respectively. Suggested antenna construction is made up of a circular patch antenna configuration and a unique EBG structure at the ground level. The suggested antenna's bandwidth is 260 MHz at 4.5 GHz operating frequency and 800 MHz at higher operating frequency like 5.2 Gigahertz and 5.6 GHz. At resonant frequencies of 4.5 Gigahertz, 5.2 Gigahertz, and 5.6 Gigahertz, the suggested antenna obtained gains of 3.28 dBi, 5.39 dBi, as well as 4.43 dBi, respectively. The antenna presented meets the requirements of multiband applications.
