Antennas

The future is FAST. 5G networks will accelerate data up to 100 times faster than today's technology. This will require advanced connectivity for broader bandwidth and high-clarity communications. Increased data speeds in the future will enable an interactive ecosystem for a smarter, productive, and connected world. Read more...

Our broad portfolio of antenna technologies includes standard antennas and custom antennas, with two shot molding, stamped metal, flexible printed circuit (FPC), printed circuit board (PCB) and laser direct structuring (LDS) solutions. Read more...

Frequently used conversion factors, how they are derived, and why they are used. If you need to convert from one series of units to another for any reason, this is the tech. note for you. Read more...

QuinStar’s QRC Cassegrain Reflector Antennas are available in diameters ranging from 10 inches to 4 feet (25 to 120 cm) for any frequency in the 18-140 GHz range. They operate over a fairly wide frequency range, limited only by the circular waveguide bandwidth.

Gain is determined by antenna diameter, frequency of operation, and feed illumination. These antennas are typically... Read more...

QuinStar Technology's QLA series lens antennas are available with apertures ranging from 3 to 12 inches (76-300 mm) for any frequency in the 18-140 GHz range. These antennas consist of a lens which is fed (illuminated) by a specially-designed feed horn. Read more...

Depending on the type of test that antenna may include factors such as:
• Loss due to mismatch of impedance between the antenna output and transmission line.
• Loss due to attenuation of the transmission line.
• Loss due to VSWR at the and/or the receiver.
• Gain due to a preamplifier located at the antenna. Read more...

This is a brief overview on how to perform a standard Radiated Emissions Measurement test. It includes how to set up, take measurements and calculate results. Read more...

An antenna's antenna factor (AF) is a comparison between the field level presented to the antenna and the actual voltage produced by the antenna at it's connector. Read more...

A.H. Systems' Tuned Dipole Set provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.4). Each Tuned Dipole Set is manufactured per the FCC balun design and is individually calibrated.All sets come contained in a rugged, lightweight storage case which includes four baluns, elements, cables, a tape measure and one clamp for tripod mounting. Read more...

A.H. Systems' Active Monopole Antenna provides superior performance in electric field measurements. The Active Monopole Antenna can drive any receiver with 50 ohm input impedance and will perform FCC, MIL-STD and TEMPEST tests. The SAS-550-1B includes a battery pack and charger for open field test sites that may not have ready access to outlets. Read more...
