Guidance with exercises

  1. These exercises will be handed out at the beginning of the instructions.

Design of the active antenna

  1. Which functions should be performed by the active antenna?

  2. Extract the environmental operating conditions from the application description.

  3. Extract the cost factors from the application description.

  4. Which performance measures are given in the application description?

  5. At this stage, do you notice conflicting requirements?

  6. At this stage, do you notice redundant requirements?

  7. At this stage, do you miss any requirements?

  8. Summarize the above (1-7) in an ‘Object Performance Specification’ and an ‘Object Test Specification’

    The SLiCAP format for these specifications is found in: Day1SLiCAP.zip.

  9. The whip antenna itself converts E-field into voltage, while the output impedance of the antenna amplifier should be 50 \(\Omega\).

    1. Give the desired values of the transmission-1 matrix coefficients for this amplifier.
    2. Verify your answer with SLiCAP. Please use the SLiCAP input format for the active antenna as given in the designExample.zip file.

  10. Could we also use the short circuit current as input quantity for the antena amplifier? Motivate your answer.

  11. If we would use the short circuit current of the antenna as input quantity for the amplifier:

    1. Give the transmission-1 matrix parameters for this amplifier.

    2. Verify your answer with SLiCAP.

      Tip: SLiCAP does not allow the use of thr Laplace variable ‘s’ in parameter definitions. Please select an appropriate model from Figure 2.22 in the course book.
