Optenni Lab — List of main features

The main features of the Optenni Lab software are:

  • Capability of reading multiport S parameter files of the load (antenna) impedance in the Touchstone format (S or Z parameters)
  • Specification of complex frequency-dependent termination impedance for each port
  • De-embedding the effect of a measurement cable
  • Automatic generation of matching circuit topologies and optimization of component values
  • Preset frequency range data for many wireless systems (GSM, WCDMA, TD-SCDMA, 3GPPP bands, WLAN, BT, navigation etc.)
  • Component library of commonly used inductors and capacitors
  • Tolerance analysis of the generated matching circuits
  • Simultaneous multiport matching
  • Modeling of component losses and optimization of the transducer power gain or the impedance match of the matching circuits
  • Optimization of matching circuits where the topology and some component values have been fixed using inductors, capacitors, resistors, transmission lines, S parameter blocks
  • Support for tunable S parameter blocks in the S2PMDIF data format, indexed by one or multiple variables
  • Specification of complex matching circuit topologies including series and parallel resonators
  • Specification of different optimization targets for different frequency bands and specification of stop bands
  • Plotting the two-port S parameters of the matching circuit and together with mismatch loss, component losses and total efficiency through the matching circuit
  • Interactive tuning of the matching circuits
  • Generation of matching circuits that obtain conjugate matching to the termination impedance or maximize the bandwidth around a starting frequency
  • Visualizing the impedance trace of a matching circuit at a single frequency on the Smith chart
  • Calculation of the system S parameters when one of the ports has been terminated with a matching circuit
  • Saving system S parameters, matching circuit S parameters and input impedances as Touchstone files
  • Saving plots in various file formats (.jpg, .bmp, .tiff, .png, .pdf, .ps) and saving plot data as text files
  • Estimation of the obtainable impedance bandwidth through matching circuits using the bandwidth potential and Q value techniques
  • Estimation of the obtainable efficiency bandwidth through matching circuits with a predefined topology and tunable components
  • Calculation of the antenna radiation efficiency from the total efficiency and impedance data
  • Calculation of the electromagnetic isolation (worst-case isolation) between two ports of a multiport system
  • Capability to save and load project files containing the previously computed results
  • An easy-to-use graphical user interface where all the previously computed results are available in a result tree
  • A two-way link with CST STUDIO SUITE™
  • A link to Microwave Office™
  • On-line manual
