Design of Multi Switch Operation Mode Rectenna Device for 2.4 GHz Frequency Band Wi-Fi and Bluetooth Based On Microcontroller ATmega328

This research contains the design of an automatic multi switch to manage the activity of rectenna as an electromagnetic energy to DC voltage converter and Wi-Fi or Bluetooth devices that works on 2.4 GHz frequency band. Energy harvesting is one of the alternative ways of energy conversion; the process produces energy that can be used by devices that need a small amount of power. However, the existence of rectenna around telecommunication devices can interrupt the power absorption of these devices. To solve this problem, we need a device that can manage the work of rectenna and the devices so the interference can be reduced and the utilization of electromagnetic energy on 2.4 GHz frequency band will become better.
