Spherical Near-Field Antenna Measurements

 




Spherical Near-Field Antenna Measurements

Characterize your antennas completely with spherical near-field measurements

Spherical near-field measurements allow the complete characterization of antenna designs. To perform the near-field measurements the antenna under test is rotated in two axes while a fixed probe measures the field data over the spherical surface.

The 700S-30 spherical near-field scanner from Nearfield Systems Inc. (NSI) provides the mechanism for positioning accurately both the antenna and the test probe while performing the measurements. The 700S-30 uses a dual axis phi-over-theta high accuracy stepper motor to position the antenna under test. It allows full spherical 360º phi/theta rotation of the antenna, with a resolution of 0.0125º in both axes and a rotational speed of 20º per second.

In order to measure the antenna performance the 700S-30 can be interfaced to a variety of Agilent Technologies RF and microwave test equipment including the PNA series microwave network analyzers. With the 700S-30 spherical near-field scanner interfaced to an Agilent PNA you can characterize your antenna design accurately and completely.
