IEEE International Symposium on Electromagnetic Compatibility | Year: 2016
An analysis of electromagnetic radiation reduction achieved by placement of microwave absorbers over a serial high speed digital channel is performed. The study is performed on a second generation peripheral component interconnect express (PCIe Gen II) interface with 5.0 Gbps transfer rate. A set of full wave simulations are performed on a printed circuit board with the PCIe interface implemented in an embedded micro-strip line structure. Lossy material patches are applied onto the channel to reduce the electromagnetic radiations from differential pairs. This reduction might be required especially in compact mixed signal systems as noisy digital circuits are located close to radio-frequency receivers with stringent sensitivity limits. Using the numerical solver, it has been shown that the application of the absorber can reduce the magnitude of the received electromagnetic fields at the desired locations while unfortunately affecting the signal integrity performance of the bus. In order to reduce the unintentional discontinuity introduced along the differential pairs as applying the material on the PCB, the insertion of a dielectric spacer sheet between the absorber and the solder mask is investigated. It has been shown that the presence of a thin layer of the spacer (less than 0.2mm) can significantly decrease the introduced mismatch while still keeping the benefit of the EM reduction. Full wave simulation results are being confirmed by near field probing set-up and a PCIe compliance test board. © 2016 IEEE.

This paper presents the results of experimental study of passive intermodulation (PIM) generation in microstrip lines with U-shaped and meandered strips, impedance tapers, and strips with the profiled edges. It is shown that the geometrical discontinuities in printed circuits may have a noticeable impact on distributed PIM generation even when their effect is indiscernible in the linear regime measurements. A consistent interpretation of the observed phenomena has been proposed on the basis of the phase synchronism in the four-wave mixing process. The results of this study reveal new features of PIM production important for the design and characterization of low-PIM microstrip circuits. © 2010 IEEE.

Proceedings - 2011 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications, APWC'11 | Year: 2011
The correlation coefficient between the received signals from a pair of antennas is a parameter which provides information about the performance of an antenna pair in diversity and MIMO applications. In case the correlation coefficient is low, a deeper assessment of the antenna performance can be made by investigating the cause for the low correlation coefficient. A separation of the correlation coefficient into two factors is proposed. The factors reveal to what degree it is amplitude variations (complementary coverage) or phase difference variations over the sphere that is the cause. Expressions for the proposed factors are presented, and examples are given in which the proposed factorization is motivated. © 2011 IEEE.

The demands of environmentally friendly and whisker-generation-resistant board level shields are increasing with endless marking requirements for high EMC performance and cost-effective electronic products. As a result, some environmentally friendly composite plating steels, such as chromate-free electrogalvernized steel (ZE-38) and ECO-TRIO steel, have been developed and emerged as promising board level shielding materials. This paper assesses and evaluates the acceptability and performance of these materials in accordance with the requirement of board level shielding applications. With good solderability, high resistance to whisker generation, relatively high surface conductivity, and satisfactory corrosion resistance, the ECO-TRIO and ZE-38 steels have great potential to take the place of Tin plated cold rolled steels and Nickel Silver alloys as next generation board level shielding materials. © 2010 IEEE.
