pat be used as the file name extension, but this is not necessary as a. So that the program can properly normalize the values for internal use, the azimuth and elevation with the maximum pattern value in each case must be included in the file. A comma and/or spaces can be used to separate the fields on each line. In preparing the file, actual, numbers are used in place of the variable names. The structure given above is in generic variable name array notation. In this case the EDX program will assume unity gain for all vertical elevations at all azimuths. This line will then be the last line in the file. If there is no vertical plane pattern information, the NUM_SLICES and NELV values should both be 0. Both horizontal and vertical plane pattern values can be listed in the file.Ĥ1EL(NUM_SLICES,NELV), VP(NUM_SLICES,NELV) This file is a tabulation of azimuths and relative field or dB values that describe a single section or slice of a 3-dimensional antenna pattern. This is an ASCII data file you can prepare yourself to use a text editor or using the 2-dimensional antenna pattern file creation utility function (see Create/Edit a 2-Dimensional Antenna Pattern File ). To use 3-dimensionsal antennas, including beamforming and MIMO antennas, with EDX software, the data describing the 3-dimensional patterns must be stored in a file, same as in the 2-dimensional case. The more data you can include (ie the more azimuths and gains) the more accurate your pattern should display and give results.īelow is a sample of the converted pattern from the linked sample. If you have 2 or more slices, you will need to list the value in degrees that each slice is based on. If only utilizing one slice, your pattern is complete. List all vertical azimuths and gains in each slice from -90 to 90. On the next line begin to list out the vertical slice. Next, list in two columns all of the horizontal azimuths and their associated gains, either 0 to 360 degrees, or -180 to 180, with a maximum increment between azimuths of 45 degrees.īelow that enter how many slices you have and the number of points or values within each slice. This will be the antenna name in single quotations, the maximum gain of the antenna, and the value signifying whether the following tabulated pattern data is in relative field strength or relative dB.
