Comparison of Conversion Algorithms
Four interpolation algorithms are visually compared when looking at the resulting 3D patterns and the other hand analytically when using the resulting 3D patterns for the path loss prediction. For the comparison three different antennas from Kathrein are going to be evaluated with different values concerning the horizontal and vertical half power beam width (HPBW):
Name | Type | Frequency | HPBW (H) | HPBW (V) | Max. gain | Elect. tilt |
---|---|---|---|---|---|---|
741 794 | X-Pol | 2110 MHz | 65° | 7° | 18.5 dBi | 2° |
741 984 | X-Pol | 1855 MHz | 87° | 26° | 11.5 dBi | 0° |
742 211 | X-Pol | 1855 MHz | 67° | 14° | 15.5 dBi | 6° |
As a reference for the comparisons always the measured 3D antenna pattern is available (in all three examples). These measured 3D patterns are provided by the manufacturer of the antennas (Kathrein).
In the following an individual subsection is dedicated to each antenna, comparing the results of the different interpolation algorithms (on the one hand by the resulting 3D antenna patterns and on the other hand by predictions of the received power when using the corresponding interpolated 3D antenna).
