In order to enhance the functionality of Internet of Things (IoT) nodes in real-worldambient settings, a hybrid methodology is used that integrates power from both radio frequency (RF) and direct current (DC)sources. This strategy utilizes certain frequency bands, including GSM 900, GSM 1800, Wi-Fi 2.4 and LTE 2600 GHz bands, toprovide the desired power supply. A circularly polarized bowtie-log periodic antenna with a ring-like central framework andasymmetric slots facilitates more accurate matching in the top four frequency bands and multiband consequence, whereascircular shapes loaded within an open rectangular antenna are used in the lower frequency bands. The proposed approachfor achieving consistent rectenna output under numerous levels of input power and resistances to loads involves the use of amodified π- network with microstrip matching elements. The dc rectification efficiency is highest at 73.30% (at 0.9, 1.8, 2.1, and2.44 GHz for - 17.5 dBm input power level), and 61.8% (at 0.9, and 1.84 GHz for - 14 dBm input power level), individually for thevalue of load resistance at 6.1 kΩ. The DC output voltage that is generated in the system is 464.5 mV to 492.2 mV for indoorand ambient environments, respectively. The encouraging outcomes in both indoor and outdoor environments are great forpowering IoT devices that consume low-power.
