Simulation Results
The following results show the expected performance of WB002 when using a full ground plane as shown in
the layout files in section 3.
Radiation patterns
The following plots show the expected radiation patterns for different antenna orientation.
Group Delay Variation
Group delay variation is an important parameter to consider for antennas to be used in location solutions using IR-UWB such as DW1000. Here we mean how the group delay of the antenna changes as the antenna is rotated. 1ns of variation would represent 30 cm variation in the reported distance, so we aim for a group delay
variation with antenna rotation of <±100 ps. The plot below shows the variation in group delay as the antenna is rotated. The scale is in nanoseconds and as can be seen there is very little variation with the antenna.
