This is a bunch of python scripts to simulate, analyze and plot the results of different simulations conducted in STK and CST Microwave Studio.
There are basically three different parts:
- CST result analysis
- STK result analysis
- Python scripts for simulating the fields of phased array and patch antennas
The main script that analyzes the CST results is CSTResultLoader.py. It takes the steering sweep simulation results from CST and parses it to plot Heatmaps. The plotCSTHeatmap.py can also be used but does not provide as much functionality (legacy script).
The STK scripts are rather self-explanatory according to their title. Each of them has to be adjusted so that the path to the simulation results is correct.
The antenna toolbox consists of 3 class definitions: Antenna.py, RectangularArray.py and RectangularPatch.py, where the two latter inherit important methods as the plotting of the 3D pattern or pattern cuts from Antenna.py. All classes support the calculation of the normalized pattern function and antenna directivity.
For example, an antenna with an arbitrary precomputed field can be instantiated by:
patch = Antenna()
patch.loadPatternFromFile("sim/patch_8Ghz_efield_ro5880_0.254.txt")Using the following, a rectangular array can be instantiated.
In this example, the previously created patch will be set as element pattern.
paa1 = RectangularArray(4,4,0.5,0.5,f,arraytype="uniform",sidelobe_level=30)
paa1.setElement(patch)
paa1.getArrayFactor(0,180,1,0,360,1,0,0)
paa1.getField(0,0)
paa1.calcDirectivity()The full_paa_comparison.py script shows more functionality of this toolbox.
