The
IsoFilterTM Antenna Measurement
Technique: Extending the Measurement and Analysis Technique to
Antennas Mounted off the Range Axis
 Dr.
Doren Hess, Senior Staff Engineer at MI Technologies, introduced a
new measurement and analysis technique at the Antenna Measurement
Techniques Association's annual symposium last October. In this
second segment of a two-part series, the MI Communicator offers Dr.
Hess' second paper: "The IsoFilterTM
Technique: Extension to Transverse Offsets"
In this paper, Dr. Hess presents
the theory behind the IsoFilterTM
technique and shows how it can be used to remove unwanted signal
interference from spherical near-field antenna measurement data.
This technique is useful in a variety of measurement situations when
antennas under test are mounted on or near ground planes and other
reflecting surfaces such as automotive and aircraft antennas and
antenna arrays.
The end result of the IsoFilterTM
technique yields an approximate far-field antenna pattern of the
individual radiator largely uncontaminated by the unwanted
interference.

MI-4190 Position Controllers
Offer Precision Control for up to 16 Axes of Motion!
MI Technologies' MI-4190 Family of Position Controllers offers the
best solution for motion control applications -- from antenna and
radar targets under test, to precision placement and rotation of
tools, or instruments in test facilities or remote field locations.
The easy-to-use microprocessor-based controllers combine manual and
automatic position control, position display and program functions
for up to 16 axes of motion.

MI Technologies to Upgrade
Technical University of Denmark's Antenna Test and Measurement
System
MI Technologies has received an order from the Technical University
of Denmark (DTU) to provide an upgrade to its at its Ørsted DTU
campus in Lyngby, Denmark near Copenhagen. The equipment will be
used in the design, development and validation of space-related RF
projects.

Oakland University Selects MI
Technologies' Telematics Test System
MI Technologies will design,
build and install an outdoor spherical near-field antenna
measurement system for Oakland University, in Rochester, Michigan.
The University intends to use the new test range to perform
'on-vehicle' antenna testing in S-Band for the Satellite Digital
Audio Radio Service, (SDARS).
