|Near-ï¬eld measurement is suitable for a variety of antennas, from small antennas in compact electronic devices to very large phased array antennas.|
Suited for highly directive antennas, such as phased array or satellite communication antennas.
Typically used to measure semi-directive antennas, such as base station antenna or Base Transceiver Station (BTS) antenna.
Test any type of antennas. Often used for multi-purpose facilities and are particularly suitable for wide-beam and omni-directional antennas.
Far-ï¬eld ranges are the traditional vehicle for performing antenna measurements. In situations where antenna dimensions and environmental conditions allow, this may be the method of choice because of its relative simplicity and low cost.
Outdoor far-field systems are used when real estate is readily available and environmental conditions are not a concern.
Indoor far-ï¬eld systems have become more popular due to advances in chamber design and Compact Ranges as well as an increased requirement for measurement security.
Compact Ranges replicate large plane waves at range lengths that are much shorter than possible on a conventional far-ï¬eld range.
A parabolic reï¬ector transforms the spherical wave from the feed into a plane wave at the test antenna aperture.
Compact Ranges are available in almost any size for the entire microwave and millimeter wave frequency bands.
- Serrated Edge Compact Range
The edges of these reï¬ectors are shaped as serrations, with a design that directs edge diffraction away from the quiet zone. Serration size increases as the lowest operational frequency decreases.
- Rolled Edge Compact Range
The rolled edges of these reï¬ectors minimize the generation of edge diffraction. Edge size increases as the lowest operational frequency decreases.
Radome testing solutions are used to measure Transmission Efï¬ciency, Beam Deï¬ection/Boresight Error, Antenna Pattern Distortion, Sidelobes and Reï¬ectivity of antennas housed in a radome.
- For military applications
The radome is typically tested in a variety of different positions and beam states, requiring advanced positioning capabilities and AUT control.
- For commercial applications
Testing is normally performed in accordance with RTCA DO-213 speciï¬cations.
Radar Cross Section measurement systems are necessary to measure the reï¬ectivity signature of a wide variety of objects.
Measurements are often performed in a Compact Range, requiring target support pylons for positioning the device under test while minimizing background return.
Our StingRay gated-CW RCS measurement system covers frequencies ranging from VHF to W-band with fully polarimetric options.
The Specific Absorption Rate (SAR) represents the rate at which the RF electromagnetic energy is imparted to an element or mass of a biological body.
The SAR value of the energy radiated by a mobile phone is measured in test benches, where the body of a human is simulated by a phantom filled with liquids that have the same dielectric properties as a human body.
SAR measurements are defined by international standardization committees for the certification of mobile phones.
Our SAR test systems are dedicated to the development and certification stages of mobile telecommunication equipment and are complementary to our antenna measurement systems.
Field strength meters measure the level of exposure to which a human is exposed to in a "free" environment.
These systems integrate tri-axial probes to guarantee the measurement's isotropy. Many countries have adopted international or national procedures to measure the exposure level.
We offer measurement systems that enable the measurement of this level for BTS site certification or for the continuous assessment of exposure (portable or stationary), as well as alarm systems for people working in close proximity to emitting antennas.
A transmitting antenna projects electromagnetic fields through the entire thickness of the inspected material. A sensor array measures the resulting field distribution. The collected data is then processed through software that displays the material properties at full production speed.
