ETS-Lindgren 3164-11 Open Boundary Quad-Ridged Horn 1 GHz - 18 GHz

ETS-LINDGREN€™S MODEL 3164-11 OPEN BOUNDARY QUAD-RIDGED HORN is the latest in a series of quad-ridged horns from ETS-Lindgren. The “open boundary“ design with its absence of side plates makes this antenna unique in both appearance and performance. Numerically modeled, the Model 3164-11 is a super open boundary quad-ridged horn where the feed cavity is not enclosed. This gives wider frequency range and reduces the weight of the horn.

Frequency Range
The 3164-11 antenna has a range that covers 1 GHz to 18 GHz, making it ideal for antenna measurement applications and as an EMC antenna for measuring emissions above 1 GHz.

Flat Gain
Like other open boundary quad- ridged horns, the 3164-11 exhibits a very flat gain as it changes less than 2 dB for over 80 % of the upper part of the frequency range.

Dual Linear Polarization
The 3164-11 is a dual linearly polarized horn. Two orthogonally located input ports feed two set of ridge structures, these allows the horn to measure two orthogonal fields simultaneously without the need for physically rotating the horn. The isolation between the ports is better than 25 dB across the frequency range.

Compact Design
This antenna has a smaller, lighter design in relation to other single polarized ridged horns, while exhibiting equivalent performance with the added bonus of dual polarization.

Flexible Mounting
The 3164-11 includes a mounting bracket that can be attached to any tripod or mast with a ¼ 20 thread screw. In addition to the bracket, the 3164-11 has a mounting flange that allows it to be mounted to the shield of a chamber.

Individually Calibrated
This antenna is individually calibrated at 3m per the SAE ARP 958 standard.
