A Compact Monopole Slotted Patch Antenna for Rfenergy Harvesting

Abstract
The rapid expansion of modern wireless communication systems has led to the continuous presence of radio frequency (RF) signals in the surrounding environment. These signals are produced by sources such as cellular communication networks, wireless local area networks, and broadcasting systems. Although this electromagnetic energy is normally unused, RF energy harvesting technology provides a method to capture these signals and convert them into electrical power that can support low-power electronic devices, wireless sensor networks, and Internet of Things (IoT) applications.In RF energy harvesting systems, the antenna is one of the most important components because it is responsible for receiving electromagnetic energy from the environment. The overall performance of the harvesting system strongly depends on the antenna characteristics, including size, impedance matching, bandwidth, and radiation behavior. Therefore, designing a compact antenna with efficient signal reception capability is an important requirement for practical harvesting systems.This work proposes a compact monopole slotted patch antenna intended for RF energy harvesting applications. The antenna structure incorporates slot features in the radiating patch to modify the surface current path, which helps improve impedance matching and broaden the operating bandwidth. The design parameters are analyzed and optimized to achieve efficient radiation and reliable performance within the desired frequency range. Simulation results indicate that the proposed antenna provides satisfactory reflection coefficient characteristics and stable radiation performance, demonstrating its suitability for capturing ambient RF energy for low-power wireless applications.
