NSI-MI Technologies has an extensive history in the development of innovative antennas for precision antenna test and measurement applications, as well as other wireless applications. NSI-MI antennas are designed, developed and manufactured in our factory by our talented staff of antenna design engineers with decades of experience. Our antenna products and services fulfill the needs of numerous markets, including the military and defense, aerospace, automotive, satellite communications, and wireless industries.
Broadband Ridged Probes
NSI-MI offers broadband ridged probe (BRP) antennas for use as spherical near-field (SNF) measurement probes and far-field (FF) range illuminators.
Quadridge Horn Antenna
The dual linear polarized horn antennas suitable for a wide variety of applications that require stable antenna performance over broad frequency bandwidths.
Focused and Aligned Parabolic Reflectors and Waveguide Feeds
Each product in this family consists of a weather sealed waveguide horn with a radome cover.
NSI-MI Technologies' Waveguide Feeds are linearly polarized pyramidal horns. They cover frequency ranges from 1.1 GHz to 40 GHz.
Linear Log-Periodic Antennas
The ANT-LLP Family of Linear Log-Periodic Antennas are log-periodic dipole arrays designed to have nearly constant gain and input impedance over a broad frequency range.
Dual 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.
Standard Gain Horn and Coax-to-Waveguide Adapter Assemblies
Our Standard Gain Horns cover the frequency range from 0.32 to 170 GHz. Horn dimensions and calibration data are taken from NRL Report 4433. Gain versus frequency charts based on the NRL report are supplied with each unit.
Standard Gain Horns
The Family of Standard Gain Horns cover the frequency range from 0.32 to 170 GHz. Horn dimensions and calibration data are taken from NRL Report 4433.
NSI-MI Technologies' ANT-CWA Family of Coax-to-Waveguide Adapters offers a convenient transition between waveguide and coaxial transmission lines.
Linear Polarized Feeds
The ANT-LPF Family of Compact Range Feeds offer a complete line of linearly-polarized high performance feeds covering frequencies from 0.75 to 40 GHz.
The ANT-DPF feeds combine a high performance broadband orthomode transducer with precision circular waveguide feeding a circularly symmetric waveguide aperture.
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.
