Active multiband GNSS dual feed, stacked patch Antenna for superb positional accuracy
The ADFGP.55A is a precision-engineered active dual feed, dual patch multiband GNSS antenna. Designed for GPS (L1/L2/L5), GLONASS (G1), Galileo (E1/E5a) and BeiDou (B1/B2). The antenna comes mounted on a 50*50 mm PCB (ground plane). It consists of two stacked patches, 50mm, and 40mm in width and is 17mm thick. It has been tuned and tested on a 50*50mm ground plane specifically for GPS L1: 1575.42MHz, L2: 1227.6MHz and L5: 1176.45MHz as well as the GLONASS, Galileo, BeiDou and IRNSS bands shown in Section 2 of the product datasheet.
Each patch element uses two orthogonal feeds that are combined in a hybrid coupler to ensure optimal axial ratio. The antenna exhibits excellent gain and good radiation pattern stability leading to a reliable GNSS fix in areas of weaker signal strength. All these elements combined ensure the best possible positional accuracy for your device. Both patch elements have a dual pin feed to ensure a low axial ratio and should be used in conjunction with a hybrid coupler. The ADFGP.55A includes the upgraded anti-noise capability, LNAs and front-end SAW filters to reduce out of band noise, such as from nearby cellular transceivers. It offers better protection from nearby radiated power surges and greatly reduces the probability of damaging your GNSS receiver from nearby transmissions.
Typical applications include:
• UAVs and Robotics
• Transportation
• Autonomous Vehicles
• Agriculture
• Navigation
• RTK
The ADFGP.55A is connected via an I-PEX MHF1® connector and works well without modifications in most environments, however, it can be tuned and optimized for different ground planes and enclosures if required. Custom antenna modifications are subject to possible NRE and minimum order quantity.
