New Compact Antennas Offer Big Performance

Cedar Park, Texas, June 27, 2007 – ETS-Lindgren announced the addition of two new antennas - 3164-06 and 3164-07 - to its family of open boundary quad-ridge horn antennas. Adding these compact sized antennas extends the family's frequency range from 300 MHz to 18 GHz - allowing pattern measurements covering the UHF, and the L, S, C, X and Ku bands. Big on performance, the 3164-06 (300 MHz - 6 GHz) covers the main wireless bands and the entire UHF band common in tapered chambers. The 3164-07 (700 MHz – 6 GHz) also covers the main wireless band and is ideally suited as a source for use in rectangular chambers. The existing antenna in the family, the 3164-05 (2 GHz – 18 GHz), can be used as a source in both tapered and rectangular chambers. Additionally, the 3164-05 can be used with parabolic reflectors and as a source in compact ranges with a slight reduction in QZ size at the high part of the range.

Dr. Vince Rodriguez, ETS-Lindgren's Senior Principal Antenna Design Engineer, noted, "Engineers in the military defense and commercial markets increasingly need to perform antenna pattern measurements at lower frequencies. Using the advantageous open -boundary quad-ridge design, the 3164 family of antennas meet the performance objectives and provide a more stable antenna pattern at the upper end of their frequency range. The antennas are also equipped with dual ports, so simultaneous measurements can be made in two orthogonal polarizations of the field. And, using a 90-degree hybrid (not supplied), the antennas can transmit or receive circularly polarized waves."

The 3164 family of antennas can has flanges for wall mounting and a bracket for tripod mounting. The rear assembly of the antenna is milled from a solid block of material; when the antenna is correctly wall mounted in an enclosure, RF leakage (in or out) is virtually non-existent. The 3164 series antennas are individually calibrated and available for immediate delivery with quantity pricing. For more information:
