The design and simulation of a dual-band rectangular patch antenna array at 2.4 GHz and 3.5 GHz for Zigbee and Wimax applications are presented in this paper. The suggested antenna is expected to meet the wireless connectivity requirements in the architecture of a literature-inspired pre-hospital emergency system using IOT (Internet of Things) technology. In recent years, the rapid growth of IoT technology in the medical field has been observed. Introduced to support large-scale reconstruction

The simulations were performed with the help of ANSYS High Frequency Structure Simulator (HFSS). The radiating element and the feed line are constructed with the material PEC (Perfect Electric Conductor) of 0.035 mm thick. They are engraved on an Epoxy FR-4 substrate, with a relative permittivity ℇ𝒓= 4.4, thickness h = 1.6 mm, with the resonance frequency 𝒇𝒓 = 2.45 GHZ. Epoxy FR-4 is chosen as the substrate material because it is very affordable in terms of cost and has superior and outstanding mechanical properties, making it suitable for a wide range of applications on an electronic component. A micro strip patch antenna array can improve the gain in order to use our antenna in emission for the wimax band thus ensuring the transmission of data from the ambulance to the hospital. We have identified a gain improvement of 51.45% for the array antenna when compared to the normal micro strip patch antenna.
