VNA Impedance Measurement for Power Distribution Networks
Indianapolis, February 28, 2019 -
Copper Mountain Technologies
(CMT), along with Compass Technology Group, has a webinar entitled "A New Method for Dielectric Property Measurements" coming up
on Thursday, February 28, at 11:00 am EST.
Dielectric properties are important for design of antenna and wireless technologies.
As the internet of things, 5G, automotive sensing, and other advanced technologies
become more prevalent, product designers and manufacturers require accurate material
properties for ensuring their devices operate as desired. This webinar will provide
information about dielectric materials measurements and introduces a new dielectric
measurement method, called the "epsilometer." This method was developed to make
dielectric property measurement accessible to the device designer. Not only was
it designed with advanced computational electromagnetic design tools, but it was
specifically engineered to make dielectric measurements both affordable and easy
to do. This webinar will overview the new epsilometer method and give examples of
how it can measure a variety of dielectric materials used to manufacture of wireless
devices (e.g. substrates, radomes, etc.).

A New Dielectric Analyzer for Rapid Measurement of Microwave
Substrates up to 6 GHz
This paper from Compass Technology Group
presents a new measurement method based on the parallel plate capacitor concept,
which determines complex permittivity of dielectric sheets and films with
thicknesses up to about 3 mm. Unlike the conventional devices, this new method
uses a greatly simplified calibration procedure and is capable of measuring at
frequencies from 10 MHz to 2 GHz, and in some cases up to 6 GHz. It solves the
parasitic impedance limitations in conventional capacitor methods by explicitly
modeling the fixture with a full-wave computational electromagnetic code.
Specifically, a finite difference time domain (FDTD) code was used to not only
design the fixture, but to create a database-based inversion algorithm. The
inversion algorithm converts measured fixture reflection (S11) into dielectric
properties of the specimen under test. This paper provides details of the
fixture design and inversion method. Finally, example measurements are shown to
demonstrate the utility of the method on typical microwave substrates.

About Copper Mountain Technologies
Copper Mountain Technologies develops innovative RF test and measurement
solutions for engineers all over the world. The company's headquarters is in
Indianapolis with sales offices in Singapore and Miami. The company pioneered
metrology-grade USB VNAs in 2011 and continues to push for innovation and change
in the industry to ensure engineers have access to the best technology. CMT
achieved ISO 9001:2015 certification in 2019. The calibration lab in the USA is
accredited in accordance with the recognized international standard ISO/IEC
17025 (2017) and meets all requirements of ANSI/NCSL Z540-1994-1. All CMT VNAs
include application and automation support, and years of our engineering
expertise at your disposal.
Copper Mountain Technologies provides a broad range of USB vector network
analyzers, calibration kits, and accessories for 50 Ohm and 75 Ohm impedance.
CMT VNAs are used for RF and Microwave applications from 9 kHz to 110 GHz by
engineers in industries like defense, automotive, materials measurement,
medical, broadcasting, and telecommunications.
Copper Mountain Technologies' VNAs include an RF measurement module and a
software application which runs on any Windows PC, laptop or tablet, connecting
to the measurement hardware via USB interface. The user can take advantage of
the latest OS, processing power, larger display, and reliable performance of an
external PC, as well as lower total cost of ownership and simplified maintenance
of the analyzer. The result is a faster, more effective test process that fits
into the modern workspace in lab, production, field and secure testing
environments. This creative approach made Copper Mountain Technologies a leader
in the industry and earned them both the 2015 Frost & Sullivan Global Leadership
in Innovation Award and the 2017 Product Leadership Award.
