Objectives: To design high gain square slots loaded dual-band rectangular microstrip patch antenna having harmonic suppression capability and rectifier circuit (Rectenna (Antenna + Rectifier) for Radio Frequency Energy Harvesting (RFEH). Methods: To achieve the objectives, the square slots are loaded on the four corners of the rectangular microstrip patch in order to enhance the current distribution which resulted in improved impedance matching at desired frequencies with dual isolated bands. The proposed antenna is simulated in Computer Simulation Technology (CST) Studio Suite Three-Dimensional Electromagnetic Simulation (3DEM) software. A rectifier with an LC impedance matching network is designed, simulated, and optimized in Agilent Advanced Design System (ADS) software. Findings: The overall size of the proposed antenna operating at 2.49 GHz and 3.73 GHz (WiMax) is 57×48×2.5 mm 3 . The proposed antenna is assessed in terms of its simulated performance parameters: Return loss (S1,1), Impedance (Z1,1), Voltage Standing Wave Ratio (VSWR), Gain, Directivity, and Efficiency. The proposed antenna exhibits improved performance over the conventional rectangular patch antenna, in terms of (S1,1), Impedance (Z1,1) and Gain. The results obtained from the simulation indicate -35.47 dB and -37.42 dB of S1,1 at 2.49 GHz and 3.73 GHz respectively with the Gain of 4.74 dBi and 3.62 dBi respectively. Further, a rectifier circuit is proposed at 2.45 GHz. The complete rectenna system is simulated over a range of input power levels (1dBm-10dBm) for 4.7 kOhm load resistance. The simulated rectenna result presents the maximum output voltage of 3.34 V. Novelty and Applications: The proposed rectenna design with its harmonic suppression capability can be used for RFEH to drive the Internet of Things-Sensor Network (IoT-SN) and Wireless Sensor Network (WSN). The novelty of the proposed work is harmonic suppression capability. harmonic suppression capability is achieved by inserting the square slots at the four corners of the conventional square patch. https://www.indjst.org/

Advancement of modern society is required to address the power issue. Previously the energy harvesting techniques were taken into consideration without knowing their probability to work in another setting. To capture energy from radio transmissions, a microstrip antenna is designed in the paper. Gathering of energy from nearby sources for energy harvesting is an alternate strategy for low-energy use. A continuous supply for energy harvesting from radio frequency signal has similar effect as the ones from known sources like wind and solar. The arriving low-amplitude signals are demanding larger number of antennas alternatively for greatest amount of required energy. Microstrip patch antenna is in use because of its low profile, simplicity of configuration, and low rate of consumption to reduce the energy resources. The simulations on CST software and fabrication are performed to increase the power generated to charge a greater number of low-power devices using Radio Frequency Energy Harvesting (RFEH) for the ISM frequency band of 2.46 GHz. The microstrip patch antenna provides a result having return loss coefficient of 26.42 dB, Voltage standing wave ratio (VSWR) of 1.1, and a directivity of 6.14 dBi at ISM frequency band with operating frequency of 2.46 GHz. An EM signal of 1.4v source voltage is achieved, which after rectification gives an output voltage of 3.5 V. Additionally, the setup in conjunction with the suggested antenna design offers the highest level of energy efficiency. The achieved outcomes are effective and can be used to resolve some of the power problems faced by the technical world.
