The Microwave Vision Group (MVG) offers cutting-edge technologies for the visualization of electromagnetic waves. With advanced test solutions for antenna characterization, radar signature evaluation, and electromagnetic measurements, support is provided for company R&D teams in their drive to innovate and boost product development.
MVG offers a range of pre-compliance and certification measurement services for wireless devices, stand-alone antennas, and integrated antennas in four measurement facilities in the USA, France and Italy. In addition to advanced post-processing services, their measurement facilities offer the following measurement capabilities:
- Antenna: Gain directivity, beamwidth, cross polar discrimination, sidelobe levels, 3D radiation pattern, radiation pattern, globalstar registration and certification measurements in any polarization (linear or circular), antenna efficiency, either in transmit or receive mode, advanced post-processing.
- Over the Air (OTA): Total Radiated Power (TRP), Total Isotropic Sensitivity (TIS), Effective Isotropic Radiated Power (EIRP), Effective Isotropic Sensitivity (EIS), GPS sensitivity (TIS, UHIS, PIGS, ICD).
- MIMO: Multiple-Input Multiple-Outputis a wireless technology that uses multiple transmitters and receivers to transfer data at the same time.
- SAR: Specific Absorption Rate, local peak and average SAR (10 g and 1 g) in W/Kg, E-Field (V/m) measurement, body simulating tissue dielectric evaluation (permittivity, conductivity)
- HAC: M ratings (microphone mode) and T ratings (telecoil mode) with Hearing Aid Compatibility devices
The measurement systems at MVG perform cylindrical or spherical measurements, based on its indigenous probe array technology. For passive (cable-fed) measurements, postprocessing options include back projection and holography, allowing the determination of the field values at the aperture or on a particular plane or radius. As opposed to traditional single-probe mechanical scanning, MVG’s technology is based on electronic scanning of an array of probes. This technology is faster, reduces mechanical movements, simplifies mounting, reduces setup time, and improves accuracy and repeatability.
