Embedded Active GNSS Dual Stacked Patch Antenna
The ADFGP.50A is an active dual feed, dual patch multiband GNSS antenna. Designed for GPS L1/L2/L5, GLONASS, Galileo and BeiDou. It consists of two stacked patches, 50 and 40mm in width and at just 16.8mm 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 and BeiDou bands in Section 2 of the product datasheet.
Each patch element has dual feed to ensure low axial ratio and should be used in conjunction with a hybrid coupler. The antenna exhibits excellent gain and good radiation pattern stability leading to a reliable GPS fix in areas of weaker signal strength.
The ADFGP.50A includes an LNA and front-end SAW filter 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.50A 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.
