Step #11: Change the chart type for the inserted data series. Step #12: Modify the horizontal and vertical axis scales.So to plot the normalised radiation patterns : 1. open your data in excel sheet. 2. look for the max. gain value for particular angle, say for example its 6 dB. Now to make a plot with scale 0 to -40 dB which is most common, add 40-6 i.e 34 to all the gain. This make the highest gain of your result which is 6 dB in our example to 40 dB and ...This software uses Excel as the front end for data input and plot setting and plot the antenna parameters (S11, S21, Efficiency, Pattern) by Python scrips and xlwings. make sure the *.xlsm file and *.py has the same name and put at the same directory. choose the spreadsheet you want to plot and select the data file source form the drop down list. When acquiring simple three-dimensional (3d) trajectory data it is common to accumulate large coordinate data sets. In order to examine integrity and consistency of object tracking, it is often necessary to rapidly visualise these data. Ordinarily, to achieve this the user must either execute 3d plotting functions in a numerical computing environment or manually inspect data in two dimensions ...I'm using MATALAB R2020A with the Antenna toolbox to generate 2-D Plots of the measured Radiation Pattern (power in dBi) of an antenna, saved in an excel file. I wish to plot the Z-X Plane, and Z-Y Plane slice of the RP, but can't seem to understand how to combine the "right side" and "left side" pattern to create one plot.Antenna Yagi (OWA Yagi) was used as an antenna array element.

Ironically, this includes actual radar feedback. The data for a polar plot is given in polar coordinates, which is given as R-theta, where R is the distance from the origin (center of the plot) and theta is the angle from a reference angle ..." Now, polar plots are very useful but they are limiting in that one polar plot is only one slice of the field. Practical Antenna Handbook.
