| Sumario: | Recently, electromagnetic harvesting technologies have attracted the attention as an energy source for the future. The key element of an RF energy harvesting system (EHS) is the rectenna, which is a combination between a rectifying circuit and an antenna. The antenna receives the electromagnetic power and the rectifying circuit converts it to DC electric power. The research on antennas for EHS have been focused on frequencies below 10 GHz and only some of them in tens of GHz. The antennas for EHS that work below 10 GHz currently have many sources of energy, but the trade-o_ is their large size. Therefore, it is important to harvest energy at higher frequencies with a large amount of energy available. The new 5G network, which works about the 28 GHz band (27.5-28.35 GHz) and nearby frequencies, will be available in 2020, It will provide a large amount of available energy to be harvested. In this work, due to its light weight, easy integration into circuits and low cost, a 2x2 microstrip antenna array with circular polarization to harvest electromagnetic energy at 28 GHz band is proposed. The array has two resonance bands, one of 6.61 GHz (25.07-31.68 GHz) and a second one of 0.92 GHz (34.83-35.75 GHz). The bandwidth of the circular polarization is 0.73 GHz (27.75-28.49 GHz). At 28 GHz, an axial ratio of 0.91 dB and a gain of 10.4 dBi are presented. |
