ETS-Lindgren 3164-06 Open Boundary Quad-Ridged Horn Antenna

ETS-Lindgren's Model 3164-06 Open Boundary Quad-ridged Horn Antenna's open boundary design is similar to two double-ridged waveguide antennas orthogonally to each other. The antenna’s surprisingly compact size offers improved pattern and gain when compared with enclosed quad-ridged horns of similar dimensions. 

The 3164-06 has exceptional bandwidth, with operating frequency band for optimum performance from 300 MHz to 6 GHz. Two orthogonally placed input feeds allow this antenna to generate both linear and circular polarized measurements across the entire frequency band, without manual polarization.

The 3164-06 is the largest of the Model 3164 Series, with an operating range of 300 MHz to 6 GHz. The 3164-06 is designed as a receive antenna, but can also be used to transmit with a power handling capability of 20 W. The 3164-06 is ideal for taper chambers.

MOUNTING FEATURES

Chamber wall mounting holes— Equidistant holes around the circumference of the adapter plate accept 1/4–20 thread screws and nuts for mounting to a chamber wall.

Easy access to SMA connectors—The circular mounting plate provides the primary interface to the shielded enclosure mount panel. By fastening the mounting plate to the shielded enclosure, the two SMA connectors are on the outside of the enclosure (3164-05, 3164-06, and 3164-08 only), providing easy access. This also puts the cables outside of the enclosure, which reduces the effect of the cables on the measurement.

Security of shielding integrity—The back end of the antenna is machined of a single aluminum block, so the shielding effectiveness of the enclosure is not compromised by installation. This unique feature eliminates the need for a transmit antenna positioning device or a walk path inside the shielded anechoic chamber, both of which could present unwanted reflections of shielded anechoic chambers when installed improperly.

Maximize test range distance—The integrated mount fixture allows maximizing of the test range distance for a shielded anechoic chamber of defined dimensions.
