In this paper, we propose a compact and highly efficient Rectenna design (rectifying antenna), operating on ISM band with the center frequency of 2.4 GHz. An RF to DC conversion through Schottky diode (HSMS2860) is used to generate the dc voltage to operate a battery-less IoT Sensor for RF power harvesting using the designed Rectenna. We have achieved more than 80% efficiency through Advanced Design System (ADS-2016) simulation software at different power densities. Further, a rectenna circuit is designed using RF to DC Schottky detector diode and a microstrip patch antenna. The rectenna circuit design is simulated through ADS 2016 simulation software. The Batteryless sensor requires 2V- 2.5V dc voltage to perform an optimum performance. As per simulation and theoretical/practical modeling, we have achieved more than 80% efficiency at single Schottky diode and it's operating from 915 MHz to 5.8 GHz. Rectenna operates at lower power densities start from 0.4uW/cm. The proposed rectenna design is a possible candidate to be used as sensors/devices at a frequency of 2.4GHz with current technologies e.g. ZigBee, Wi-Fi, BLE and future probable application could be long-range radio sensor using the latest new generation LoRa technology its line of sight range between 10km-20km.
