The AntennaHome AHGG.24X is a high-performance passive antenna for applications that need accurate and reliable positioning data. This compact, rugged ceramic antenna receives both GPS and BeiDou satellite signals and is designed for use in various environments.
Because it is passive, it has no built-in amplifier. It works with GNSS modules that have their own low-noise amplifier or that are placed close to the antenna.
The part number is AHGG.241 and the frequencies are GPS 1575.42 MHz and BeiDou 1561.02 MHz. Impedance is 50 ohm, VSWR is 2.0 or lower, gain is 3 to 5 dB and polarisation is RHCP. The material is ceramic, the mounting is DIP and the size is Q x Q x 4.0 mm with Q equal to 25, 18, 15 or 12, so check which size you receive. It weighs 5 g each and works from -40 to +85 C.
Performance depends heavily on the ground plane and the placement, so follow the antenna's reference layout, keep the patch away from metal and batteries and tune the matching network if needed.
Electronics designers and hobbyists building their own GNSS boards, trackers and wearables who need a low-cost passive patch antenna.
A passive patch antenna depends on a good ground plane below it, so mount it on a board with a solid copper area of the recommended size and keep the feed line short. Leave a clear zone around the patch, avoid placing batteries or metal shields above it and check the match with a VNA if you can. Expect the received signal to be weaker than with an active antenna, so pair it with a module that has a good LNA.
