5G networks need to be designed to offer more capacity and flexibility while lowering overall systems operation expenses. This paper discusses various test solutions that can address current and future requirements for antenna verification, including conducted and over-the-air test methods.
Using proprietary modeling tools (numerical simulations to predict RF performance) along with building information modeling (BIM) during the design phase, ETS-Lindgren optimized Alter Technology's chamber configuration not only to fit perfectly into the limited space, but also to maximize the chamber performance beyond the specified requirements.
By 2030, the expected number of active IoT devices is predicted to surpass 25.4 billion. Because each country has specific certification/authorization requirements and standards, regulatory testing for Wi-Fi 6E devices is necessary.
This white paper presents the tools and techniques used to overcome limitations from unknown source model characterization and complexities of the environment for the most accurate source antenna measurements in the most complex test environments.

These three events combine to provide you with a truly universal view of the state of telco in 2022. Learn more on the website here.
The ANT-SGA Standard Gain Horn Assemblies from NSI-MI are designed to deliver accurate and reliable antenna gain measurements in antenna test range applications. These horn antennas are available to cover the 0.35 to 170 GHz frequency range.
Ophir RF offers the Model 4124 power amplifier system for applications operating from 6 to 12 GHz. The amplifier delivers a saturated output power of 25 W with a gain of over 43 dB.
The Erickson PM5 Power Meter from VDI is a calibrated calorimeter-style power meter for applications operating from 75 GHz to over 3 THz. With a sensor head featuring a WR10 input and VDI’s optional input waveguide tapers, the power meter can also be used at other frequencies. It is the standard meter for over 100 GHz of power measurement, with a range of power measurement from 1 µW up to 200 mW.
This application note describes how to measure the antenna pattern of a mm-Wave device in the R&S ATS1000 shielded chamber. The paper also covers the required calibration of the measurement setup and a possible near field to far field transformation when measuring larger devices.
Scott Burnside, senior antenna and RF engineer at Northrop Grumman, explains how Altair Feko and HyperStudy can be combined to design and optimize antennas for land vehicles, helicopters, and aircrafts.
Determining the final set of component values in a matching network can be a challenging process. Traditionally, RF engineers have had to simplify and idealize their matching circuits in schematics that are separated from the EM simulation. This simplification into a lumped element schematic requires perfect grounds and leaves out the coupling and transmission line effects of the interconnect metal and the antennas.
JFW offers the 50FHAO-XXX-100 100 watt fixed attenuator designed to operate in the DC to 3 GHz frequency range for military and commercial applications.
The SunAR RF Motion product line includes precision positioners for EMC testing, antenna measurements, and OTA testing; antennas for EMC and wireless testing, distributed antenna systems (DAS); turntables; and reverberation system design and stirrers for EMC, shielding effectiveness, and OTA testing.
