Abstract: In this article, a new Meander-Bridge Electromagnetic Band- Gap Structure was proposed for the suppression of Simultaneously Switching Noises (SSN) over a wide frequency range, with dimensions of 15 x 15 mm and a useful area of 100 mm². The equivalent model of the structure was created using lumped elements along with transmission lines. This method allowed determining the response characteristics across the entire frequency range of interest. Two boards were fabricated for conducting all the tests, including near-field and farfield measurements, S-parameter measurements, and electromagnetic wave simulations. The performance achieved a -30 dB level between the two ports in the frequency range of 1.75 to 11 GHz. To verify signal integrity, tests were conducted using ADS software at different communication rates, along with an internal near-field analysis of the PCB. Farfield measurements were also conducted experimentally. All the tests confirm the effectiveness of the proposed structure, demonstrating attenuation of SSN noise over a wide frequency band.
