Broadband Horn Antennas
Broadband Horn Antennas (ANT-BHA) are suitable for a wide variety of applications that require stable antenna performance over extremely broad frequency bandwidths.
View MoreBroadband Ridged Probes
NSI-MI offers broadband ridged probe antennas for use as spherical near-field (SNF) measurement probes and far-field (FF) range illuminators.
View MoreFocused and aligned Parabolic Reflectors and Waveguide Feeds
Each product in this family consists of a weather-sealed waveguide horn with a radome cover.
View MoreLog-Periodic Antennas
The ANT-LPA family of Log-Periodic Antennas are dipole arrays designed to have nearly constant gain and input impedance over a broad frequency range.
View MoreDual Polarized Log-Periodic Antennas
This antenna combines broadband coverage with the versatility of dual polarization. The ANT-DLP family consists of two crossed log-periodic arrays, specifically designed for VHF and UHF frequency bands.
View MoreStandard Gain Horn Assemblies
Standard Gain Horn Assemblies are available to cover the frequency range from 0.35 to 75 GHz. NRL curves are provided with each antenna.
View MoreStandard Gain Horns
Standard Gain Horns are used in antenna test range applications, and have been designed to deliver accurate and reliable antenna gain measurements.
View MoreCoax-to-Waveguide Adapters
NSI-MI Technologies' Coax-to-Waveguide Adapters (ANT-CWA ) offer a convenient transition between waveguide and coaxial transmission lines.
View MoreLinear Polarized Feeds
The ANT-LPF Linear Polarized Feeds offer a complete line of linearly-polarized high performance feeds covering frequencies from 0.75 to 110 GHz.
View MoreDual-Polarized Feeds
The ANT-DPF feeds combine a high performance broadband orthomode transducer with precision circular waveguide feeding a circularly symmetric waveguide aperture.
View MoreWaveguide Probes
NSI-MI Technologies’ open-ended waveguide probes are ideally suited for near-field measurements. These probes are used to sample the radiated electromagnetic field of an antenna under test while minimally perturbing the incident field.
View MoreDual Polarized Probes
NSI-MI Technologies offers a line of dual-linearly polarized high-performance probes covering 1.1–40.0 GHz.
View MoreQuad Ridged Feeds
NSI-MI quad ridged feeds (ANT-QRF) are used in antenna test range applications, and have been designed to deliver a wideband frequency response.
