Electromagnetic Shielding of a Bluetooth Antenna for Electric Vehicles Applying Metamaterial Structures
The article proposes metamaterials application for the electromagnetic shielding of an antenna that may be used in a vehicle’s Bluetooth communication system. The electromagnetic shielding process consists of reducing the dispersion of electromagnetic waves that affect a device of interest. The three main parameters of interest in the electromagnetic shielding process are reflection, absorption, and multiple reflections. The results of the application of metamaterials in the microstrip antenna structure are promising in these parameters. The S11 parameter decreased from -21.7 dB (2.4 GHz) to -30.6 dB with metamaterial. The RCS (cross-section radar) was optimized with the application of metamaterials, for theta and phi = 0° the RCS decreased over the entire frequency range between 2.2 GHz and 3.4 GHz, in 3.2 GHz decrease from -23 dB to -26.9 dB, a 3.9 dB reduction in RCS at this frequency. The absorption factor of the reference antenna increased from 61% to 73%.
