“…The bumps are introduced by connectors, see chapter 9 of ref. [5], which are always a point of impedance discontinuity (see purple colour of the right plot) whose pattern can be observed in all the plots included. To conclude the losses are low and it has very good impedance matching to the tester.…”

High Energy Physics (HEP) experiments have unique requirements for data communication. High data speeds, combined with extreme restrictions on materials allowed, leads to custom transmission lines. This paper will present transmission line design theory, simulation and testing methods. Transmission line designs options like flexes and rigid PCBs as well as cables will be studied. Finite Element Analysis (FEA) software packages simulate energy dissipation and quality of transmitted signals. The characterisation techniques of time-domain reflectometry and frequency-domain measurements are discussed and compared. Bit-error-rate testing is presented and its limitations for design discussed. Methods to improve quality, like three different types of equalization are described.

Abstract-In this paper, small dual layer spirals with several various ground structure are applied in the vicinity of the DDR3 high-speed circuit to achieve noise suppression characteristics up to 3.2 GHz region. For wider noise suppression bandwidth, the dual layer spirals with various ground structure, which provide high self resonance frequency (SRF) as well as inductance value, are implemented. The proposed dual layer spiral with various ground clearance dimension exhibits greater than 9 dB power noise suppression characteristics in the frequency range of interests and achieve about 50% voltage fluctuation reduction in time domain compare to the reference case model. To validate the effectiveness of the proposed model, sample PCB are fabricated and measured. It shows good agreement between the measured and simulated results up to 3.2 GHz.

Abstract-In this paper, an analytical method to characterize the frequency behaviour of Composite Right/Left Handed (CRLH) loaded printed dipole antenna is presented. One needs to determine the parameters of ungrounded reactive components realizing CRLH structures. Efficient resonant RLC circuit models based on Partial Elements Theory are presented to calculate inductance of meander line inductor and inter digital capacitor, while their capacitance is determined by Conformal Mapping Method. By using these circuit models and dispersion relation of balanced CRLH TL, negative resonance modes of antenna can be obtained. In addition, to validate the accuracy of the proposed analytical method, a prototype of the CRLH loaded printed dipole antenna is simulated, fabricated and measured.
