support with German company “Modusoft GmbH”.

• Started working in the field of metallurgical science and developed different processes
in-house for material treatment.
• Started design and development of SERVO Frequency drive in support with “GRANITE Devices” Finland.
• Release First Open Frame servo drive and start using in house projects.

• Started training for Pilger Tooling design with Korean and British Company

Chamber Reflectivity Measurement using RCS Method

• Radar Cross Section is defined as the area that can be perfectly detected back when electromagnetic waves were transmitted from its source to its target place. RCS measurement method techniques is used to define the
reflection loss performance of pyramidal microwave absorbers mounted on a wall.
• From the linear “Emp” and “Ref” measured data, one computes the RCS of the receive wall which is also the anechoic Chamber RCS. And the Absorbers reflectivity from the following formulas

Precision Multi-axis Heavy Duty Antenna Positioner

We offer an expanded line of positioning systems designed to
satisfy the most demanding applications in antenna measurement and tracking of satellite.

Our closed loop feedback system provides precise speed and positioning capability. Digital controllers and
positioners have been following the military standards for
environmental testing.
The positioning system will be used in military and civilian systems and it will be successfully installed in ground- based, shipboard and airborne applications.
The 4-axes DUT Positioner is designed to satisfy the most
demanding applications in antenna measurement and tracking of satellite. The closed loop feedback system provides precise speed and positioning capability.

Near-Field Antenna Measurement

Space & Defence Engineering Section of Patel Machinery developed a most accurate Planar Near-Field scanner systems
to cater the high frequency measurement upto 200 GHz. It can also be configured in horizontal scan plane to cater the characterization of large size, bulky in weight & gravitational sensitive antennas. We have a wide range of NF scanners available in sizes with a travel range from 0.5m to 30m. The developed scanners are four axes assembly having Polarization
positioner to support waveguide probe, linear Z-slide to manage distance between DUT and probe, linear Y-slide (vertical axis in case of vertical scanner) and precision linear X-slide (floor slide).
it’s a lightweight vertical structure with high rigidity travels and load balancing mechanism to avoid the deflection due to gravity.
The scanners are fitted with drive system based on customer applications.

Dual Reflector Compact Antenna Test Range

The far-field antenna measurement offers a quick estimation of antenna performance.

The traditional far-field concept demands a large separation between transmit and receive side, which is practically impossible for large size of antenna at higher frequencies.

The reflector-based compact antenna range offers all the advantages of far-field and simulate a far-field equivalent environment in a very compact indoor test chamber.
