ETS-Lindgren 3165-01 Absorber Nested Dual-Polarized Dual-Vivaldi Array Antenna - Manual (Page 8)

8 Introduction www.ets-lindgren.com
Model 3165-01
The Model 3165-01 has a frequency range of 700 MHz to 6 GHz, which covers
most cell phone, Wi-Fi, WiMAX ™, and GPS bands. It is designed to be nested in
the anechoic absorber lining of a chamber, and when installed in this
configuration, will exhibit very low reflectivity, even when the input ports are
mismatched. The normal incidence reflectivity is approximately -40 dB for a
majority of the frequency range.
Model 3165-02
The Model 3165-02 has a frequency range of 400 MHz to 6 GHz, although it is
usable to 7 GHz. The VSWR is less than 3:1 for more than 90% of the range.
The 3165-02 exhibits positive gain from around 500 MHz and above, reaching
gain levels of over 8 dBi above 2 GHz; the difference in gain between the two
ports is extremely small (less than 0.25 dB for over 90% of the range).
