ANTENNA DESIGN

Over the years, our engineers have been commissioned to design some of the following antenna types:

and many other types...

If you have an application, feel free to contact us for your engineered antenna solution. We have on-staff electrical engineers to design the antenna and mechanical engineers for the mechanical interface portion. Furthermore, all designs are not only tested via state-of-the-art computer simulations, but then are subjected to our anechoic chamber, our antenna test range and finally our environment chamber. You can rest assured that your design will outlive the elements. Feel free to contact us with your challenge.

ANTENNA REPAIR

With the evolving nature of the communications industry, we are routinely asked to maintain or repair specialty antennas. A majority of these specialty antennas that we have repaired have been refurbished to exceed the original manufacturers specifications. As such, we are pleased to analyze the antenna and provide a R.O.M at your request. Feel free to contact us for more information.

ANTENNA TESTING

Upon request, Antenna Factory routinely tests antennas from other suppliers, government agencies and corporations seeking independent third party verification. To meet the challenge, we have onsite anechoic chambers and antenna testing ranges with the following specifications:

Large Anechoic Chamber:

Size: 24 ft wide x 40 ft deep x 25 ft tall with adjacent control room

Frequency range: 2 to 94 GHz

Data acquisition: Fully-automated system for all range configurations, controlled by an MI-3000 Data Acquisition and Analysis Workstation running the latest MI software.

AUT Positioning Equipment: Standard systems provide four axes of AUT control in roll over azimuth over elevation over slide. There is a wide variety of positioning requirements through the use of alternate available positioning system components and fixtures.

AUT Maximum Test loads: Up to 3000 lbs.

Configuration options:

• Free-space range
• MI-5751 compact range
• MI-6920 — 3x3 planar near-field scanner with 3 ft x 3 ft scan plane Cylindrical Near Field and Spherical Near Field.

Compact range configuration: Cylindrical quiet zone (4 ft diameter and 4 ft length) with an amplitude taper of 0.5 dB or less. Total phase variation within the quiet zone of less than 10°. Test zone expandable to 6 ft horizontally x 5 ft vertically with up to 1.0 dB amplitude taper. Conditions vary near low end of the operating frequency band.

Small Anechoic Chamber:

Size: 15 ft wide x 20 ft deep x 15 ft tall with absorber, adjacent to control room.

Configuration: Equipped for planar, cylindrical or spherical near-field measurements.

Measurements: The MI-3000 can acquire most standard range parameters such as amplitude, phase, polarization and gain measurements. System parameters such as transmitter EIRP or receiver sensitivity can be measured or computed in post processing.

Data Output: A generous set of optional formats for output data reports, including ASCII test files and single and multi-curve rectangular, polar, isometrics and contour plots.

Our 140 foot Test Range is equipped with an azimuth over elevation positioner, a 20 foot low loss tower and motorized rotating head, allowing for 360° polarization adjustment.

This Range is equipped with azimuth over elevation over azimuth three axis positioner mounted on a 12 foot tower. It accommodates larger antennas and higher operating frequencies.

DUPLEXER TUNING

Utilizing our state of the art multi-million dollar RF Laboratories and our NIST trace source calibrated test equipment, we are pleased to provide duplexer tuning services. We require the transmit and receive frequencies from the customer, along with the customer supplied duplexer, and we will within one week (typical) tune your duplexer. Feel free to contact us for more information.
