Developing a Mesh for Electromagnetic Shielding of Vehicles’ Electronic Devices

Designing a new Faraday cage requires new material, which is lightweight and easy to manufacture, but metals like aluminium and steel are heavy materials. Therefore, this research aims to test the materials that can be good for electromagnetic shielding and lightweight, so copper, carbon fiber, and fiberglass have been tested to define their shielding effectiveness at the range of frequency between 320 and 960 MHz. An electromagnetic wave consists of a magnetic and electric field, so two types of antennae have been used in this research. The antennas are the Schwarzbeck USLP9143 log periodic antenna and the second magnetic loop antenna. The efficiency of the material that has been tested differs because of the frequency and the noisy source in the environment but all of them could be good materials for new composite material.
