The ADFGP.25E is an embedded patch antenna covering 1559MHz to 1610MHz. It has a dual feed, active patch design which makes it suitable for next-generation GNSS devices that require high positional accuracy in a small factor. The active patch antenna, by means of a double resonance design, has a wide-band operation over GNSS systems including GPS (L1), GLONASS (G1), Galileo (E1) and BeiDou (B1). The 25 mm patch uses a dual-feed configuration that combines both feeds with a 90° hybrid coupler to obtain an optimal axial ratio.

The ADFGP.25E includes an LNA and front-end SAW filter to reduce out of band noise, such as from nearby cellular transceivers. It offers protection from nearby radiated power surges and reduces the probability of damaging your GNSS receiver from nearby transmissions. The ADFGP.25E is manufactured and tested in a TS16949 first tier automotive approved facility.

The antenna is supplied with Ø1.13 cable and an IPEX MHFI® (U.FL compatible) connector. The patch, the PCB (ground plane), the LNA, and front-end SAW components are all integrated into a form factor of 25.1 x 25.1 x 7.5 mm. It connects via a 60mm Ø1.13 coaxial cable and IPEX MHFI® connector.

This antenna has been tuned for free space, Taoglas also provides a version of this with a 70*70mm ground plane: ADFGP.25A.07.0060A. Custom antenna modifications are subject to possible NRE and minimum order quantity.
