In this paper, a new de-embedding technique with Look-Up Table (LUT) is proposed for accurate and efficient characterization of interconnects, particularly printed circuit board (PCB) transmission lines including microstrip and stripline. LUT is pre-created to cover various fixture effects including the reference structures inside and/or outside test printed circuit boards (PCBs). The pre-estab...

This paper describes the first integrated transversal filter for feed-forward equalizers (FFE) operating above 40 Gb/s. Equalization of a 2−1 PRBS over a 9-ft and 6.5-ft cable with SMA connectors is demonstrated on-wafer at 40 Gb/s and 49 Gb/s respectively. The circuit is implemented in a commercial 0.18 μm SiGe BiCMOS process and is based on a differential distributed 7-tap fractionally spaced...

A Microstrip loop resonator sensor designed to determine the dielectric constant of a liquid is proposed. The resonator sensor designed for 1GHZ for different structure of loop is described. The sensor is implemented using planar microstrip technology. A dielectric material is placed above microstrip ring resonator. As a consequence the near field of the resonator interacts with the material un...

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL multiphysics to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate the modeling of open four and five conductors systems. We successfully demonstrated the calculation of the capaci...

This paper presents the design and results of a compact tapered U slot UWB printed monopole microstrip antenna. The planar, very small, thin UWB antenna fed by a single 50? microstrip line with truncated ground plane is excited by a coaxial SMA connector. The simulation was done using Ansoft High Frequency Structure Simulator (HFSS) software. Extensive investigations and parametric analysis is ...

This paper describes the design and realization of a transition from a microstrip line to a ridge gap waveguide operating between 95 and 115 GHz. The study includes simulations, measurements, and a Monte Carlo analysis of the assembly tolerances. The purpose of this tolerance study is to identify the most critical misalignments that affect the circuit performance, and to provide guidelines abou...

A full-wave analysis of the scattering parameters of a straight-to-bent microstrip line coupling is performed using a FEM technique. The numerical results, showing the influence played by the geometrical parameters of the structure on the electromagnetic coupling, are then employed to derive an equivalent circuit useful to be employed in CAD tools. A third order polynomial approximant useful to...
