H-slot coupled antenna design for IoT applications

In recent years, the demand for smart communications, wireless internet and IoT is rapidly increasing as technology spearheading rapid advances in different areas of communication and in day-to-day life. By automating chores, whether at work or at home, businesses and people can now gain and save more of this valuable resource. To fulfil this prerequisite, the cellular parts should be conservative and equipped for multifunction, multi-frequency band activity. An antenna is one of them. IoT end-devices typically use cable, whip, rubber duck, paddle, chips, and PCB as their antennas. For uses where the antenna must be routed along the device's body, there are variations with dual/multi-band antennas and flexible antenna structures. We can reduce the size of devices by proper design of antenna and it can also comfortable to operate multiple frequencies. From this project we can know the working of multi band rate filter by using H-slot coupled antenna with gap sleeves. The proposed design approach consists of low profile and small dimension.
