The captured energy allows to improve the efficiency of wireless communications, enables new technologies such as battery-less devices or power internet of things (IoT) devices. This paper presents a novel energy harvesting antenna design; an icosahedron-Sierpi\u0144ski fractal monopole antenna, the advantage of such a geometry is that it can capture a wide range of frequencies due to its multi-band characteristic and three-dimensional characteristics. The performance of the antenna has been simulated and compared with the already existing research. This antenna geometry has been designed using AUTOCAD2020 and simulated on COMOSOL 5.4 to operate at frequencies between 0.84GHz, 1GHz,1.6 GHz, 2.4GHz, and 3GHz.<\/strong><\/p>\n<p><iframe loading=\"lazy\" title=\"A Novel Energy Harvesting Antenna Design for Battery less IoT devices\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/x8P2Yaa-Si0?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<p data-pm-slice=\"1 1 []\"><strong>Introduction<\/strong><\/p>\n<p data-pm-slice=\"1 1 []\"><strong>Nowadays, RF energy is vastly available with the exponential<\/strong><br \/>\n<strong>increase of wireless signals, such as Wi-Fi, radio,<\/strong><br \/>\n<strong>TV and mobile phone signals (5G) which possibly allows<\/strong><br \/>\n<strong>for ambient RF to be harvested to charge low-power electronic<\/strong><br \/>\n<strong>devices wirelessly, previous research has already<\/strong><br \/>\n<strong>demonstrated that capturing these signals provide a solution<\/strong><br \/>\n<strong>to ensure the continuous, long-term operations of IoT<\/strong><br \/>\n<strong>devices at a low cost and power consumption [2-5]. Outdoor<\/strong><br \/>\n<strong>RF energy spectral measurements were carried out<\/strong><br \/>\n<strong>in Shunned; Guangdong, China, and London show that<\/strong><br \/>\n<strong>GSM900 and GSM1800 are the most promising bands for<\/strong><br \/>\n<strong>energy harvesting [3-4].<\/strong><br \/>\n<strong>However, this technique comes at a cost; power is usually<\/strong><br \/>\n<strong>the challenging feature, surveys have shown that power<\/strong><br \/>\n<strong>obtained from energy harvesting, is usually less than a<\/strong><br \/>\n<strong>few mW [7] therefore, EH is used in low power devices.<\/strong><br \/>\n<strong>There are various sources of ambient energy such as solar<\/strong><br \/>\n<strong>energy, wind energy, tidal energy, thermal energy, mechanical<\/strong><br \/>\n<strong>energy, electromagnetic energy, and so on. This<\/strong><br \/>\n<strong>study focuses on electromagnetic energy by capturing RF<\/strong><br \/>\n<strong>waves.<\/strong><br \/>\n<strong>To capture and store RF waves an antenna and rectifier<\/strong><br \/>\n<strong>circuits are needed, previous works have shown monopoles<\/strong><br \/>\n<strong>and dipole microstrip antennas can harvest 5.8 GHz frequencies<\/strong><br \/>\n<strong>and store more than 2.5 volts by using simple<\/strong><br \/>\n<strong>geometries such as rectangular and square [11].<\/strong><br \/>\n<strong>Fractal geometry has become increasingly popular in the<\/strong><br \/>\n<strong>design of antennas, because it leads to antenna miniaturization<\/strong><br \/>\n<strong>and multi-frequency behavior [1,10-12] this is<\/strong><br \/>\n<strong>due to the self-similarity fractal geometry. But it also<\/strong><br \/>\n<strong>presents a challenge since its radiation resistance can be<\/strong><br \/>\n<strong>greater than 50 Ohm [12]. A key feature when designing<\/strong><br \/>\n<strong>antennas is to match its impedance to that of the rectifying<\/strong><br \/>\n<strong>circuit 50 Ohm. Researchers in [10] have come with a<\/strong><br \/>\n<strong>a solution to this by placing embedding a metal plane in a<\/strong><br \/>\n<strong>fractal loop antenna, this not only adjust the impedance<\/strong><br \/>\n<strong>to nearly 50 Ohms, but also makes the antenna more<\/strong><br \/>\n<strong>compact.<\/strong><br \/>\n<strong>Such Geometry has proven to be beneficial in the creation<\/strong><br \/>\n<strong>of antennas, especially for RFID applications due to its<\/strong><br \/>\n<strong>miniature size and its ability to maximize gain resulting<\/strong><br \/>\n<strong>in a greater read range of RFID-based systems. In [12]<\/strong><br \/>\n<strong>two fractal geometries; Koch and Hilbert were proposed<\/strong><br \/>\n<strong>for a 950Mhz RFID system, in this paper the geometry of<\/strong><br \/>\n<strong>the antennas and their gain were compared, showing that<\/strong><br \/>\n<strong>loop geometries are beneficial in the creation of RFID<\/strong><br \/>\n<strong>antennas with a maximum gain of 2.51 dB for a Koch<\/strong><br \/>\n<strong>geometry and 1.74 dB for a butterfly-shaped antenna.<\/strong><br \/>\n<strong>In this paper, COMSOL has been utilized as the primary<\/strong><br \/>\n<strong>software to simulate the antenna, its gain, and its<\/strong><br \/>\n<strong>radiation pattern. In [13] a dipole fractal antenna was<\/strong><br \/>\n<strong>simulated to have a resonance frequency from 860 MHz<\/strong><br \/>\n<strong>to 2.48 GHz, this is useful for RFID systems. <\/strong><\/p>\n<p data-pm-slice=\"1 1 []\"><strong>The fractal <\/strong><strong>geometry used in this paper was a Koch Snowflake<\/strong><\/p>\n<p data-pm-slice=\"1 1 []\"><strong>and the Return Loss for the antenna was recorded for <\/strong><strong>the first<\/strong><\/p>\n<p data-pm-slice=\"1 1 []\"><strong> 3 iterations of the antenna.
