Giant Microwave Antenna Offers Extreme Performance

3164-01 Open Boundary Quad-Ridged Microwave AntennaCEDAR PARK, Texas, January 17, 2011 – ETS-Lindgren announced the latest addition to its family of open boundary quad-ridged horn antennas for microwave measurements. The new Model 3164-01 allows antenna engineers to perform measurements from 100 MHz to 1 GHz with a single antenna. With its ability to measure two orthogonal polarized fields simultaneously, it can be used to measure radiation patterns regardless of the orientation of the antenna under test. In addition, Model 3164-01 boasts excellent gain characteristics. It demonstrates a very flat gain performance, typically less than 2 dB variation, for the upper 2/3 of its frequency range. As with other antennas in the 3164 series, this latest antenna exhibits impressive cross-port isolation with levels better than 25 dB. Model 3164-01 is also ideal for radar pulse testing as its VSWR is lower than 2:1 from 110 MHz to 1.5 GHz.

“This antenna is unique for our horn antennas due to its size, performance capabilities, and design. At some 68 inches (174 cm) in length and 152 pounds (69 kg) in weight, it is a robust antenna that is very efficient in offering measurement capabilities over a very wide frequency range. This means one antenna can do it all for most microwave applications,” said Dr. Vince Rodriguez, ETS-Lindgren’s Senior Principal Antenna Design Engineer. “It’s interesting to note the design is not simply a scaled model of our other 3164 series horn antennas. Model 3164-01 does not have an enclosed feed cavity – this design feature not only reduced the weight, but improved the low end performance as well,” added Dr. Rodriguez.

Although the feed cavity is not present, Model 3164-01 may be mounted inside chambers and nested in RF anechoic absorber or against a ground plane. A custom antenna mount is also available. All antenna production units are individually calibrated at ETS-Lindgren’s A2LA accredited lab and are shipped with a manual, actual antenna factors and a signed Certificate of Calibration Conformance.
