Designs

At the MWI Lab, we can custom design, build and deploy any of the systems and devices listed on the right for your specific material measurement applications at nearly half the cost of the competitor’s equipment. Laboratory equipment using our technology has a broader frequency band, smaller sample size requirement, and cost less to maintain or operate. Our typical system requires minimal training to operate therefore, test engineers can be replaced with technicians.

These systems are used primarily in a Quality Assurance (QA) laboratory, in-process Quality Control (QC), and depot repair environments.

Here below is a sample of the devices we build. All measurement systems and devices we custom design are listed on the right.

Antennas

MWI_PRAxx Gaussian Beam Poly-rod antenna

X-band specs:
- Single polarity
- Frequency range 7-18 GHz
- Dimensions 24”x2”x2”
- Beam size 2.5 inches in diameter
- Weighs less than 0.5 lbs

Ku-band specs:
- Single polarity
- Frequency range 10-20 GHz
- Dimensions 24”x2”x2”
- Beam size 1 inch in diameter
- Weighs less than 0.5 lbs

Either poly-rod can be placed within close proximity of each other to create a dual-polarity setup.
These ploy-rod antennas produce a planar wave within 0.5 inches from the tip making the systems more stable for calibration and easier to reduce dB & Phase data for permittivity/permeability. They have been placed into multiple test system configurations including but not limited to; admittance tunnels, NRL reflection loss arches, robotic XYZ-Scanners, reflectometer, and surface defect detectors, for either laboratory QA test devices, in-process (online) QC devices, and hand held devices. The primary use of these antennas is to measure small resistive loaded sheet greater than 3.0 sq.in. and small composite materials parts when connected to a vector network analyzer such as the HP 8720es or 8364 / 5230 PNA.

MWI_MrBeanxxx Gaussian Beam antenna

Specs:
- Single polarity
- Frequency range 0.7-18 GHz
- Dimensions 21”x10”x7”
- Beam size 12.5 inches in diameter at 10GHz
- Weighs less than 5 lbs

This antenna produces a planar wave and has been placed into multiple test system configurations including but not limited to: admittance tunnels, NRL arches, Robotic XYZ-Scanners for either laboratory QA test devices, or in-process (online) QC devices. The primary use of this antenna is to measure resistive loaded sheet and composite materials parts when connected to a vector network analyzer such as the HP 8720es or 8364 / 5230 PNA.

E-Pods

 

MWI_LPL175 (E-pod) linear polarized eddy current sensor

Specs:
- Frequency range within the VHF band
- Dimensions 6”x4”x0.25”
- Beam size 1.5 inches in diameter
- Weighs less than 0.5 lbs

This E-pod is capable of measuring sheet material within the admittance tunnel, used as a hand held device, or as a defect detection device when placed in a XYZ Scanner or used in an online QA inspection configuration. The beam size can be adjusted for aligning the E-field for down-web or cross-web directions. It is primarily used to non-destructively measure resistive loaded sheet and composite materials at VHF frequencies when connected to a vector network analyzer such as the HP 8720es or 8364 / 5230 PNA or for hand held devices using N9923 PNA.

MWI_HHLPLxxx (E-pod) linear polarized eddy current sensor
Specs:
- Frequency range 90 MHz -1.5 GHz
- Dimensions 6”x4”x0.25
- Beam size 1.5 inches in diameter
- Weighs less than 0.5 lbs

This E-pod is capable of measuring resistive sheet material as a hand held device or used as defect detection device when placed in XYZ Scanner or can be placed in an online QC inspection configuration. The beam size can be adjusted for aligning the E-field for down-web or cross-web directions. It’s primarily used to non-destructively measure resistive loaded sheet and composite materials when connected to a vector network analyzer such as the HP 8720es or 8364 / 5230 PNA or for hand held devices using N9923 PNA. We now have a design for similar devices that sweeps over narrow bands within the VHF band.
