Active Six-Element Antenna Array for Robust GNSS Applications

The antenna array is composed of six active antenna elements and can be used for digital beamforming and null-steering in the entire GNSS frequency range.
An integrated calibration network enables to compensate any magnitude and phase drift between the channels.
The design is customizable and can be tailored to meet specific user requirements (e.g. 5 – 7 elements, planar or conformal reflector, etc.).
