GNSS antenna for special applications 2J0801

Ceramic patch antennas used for GPS applications have a significant limitation – they must face the sky in order to get the best reception. Moreover, these antennas are sensitive to the size of the ground plane area and must be tuned together with the ground plane, which is a serious drawback.

In order to eliminate these limitations and have more flexibility, 2J offers 2J0801a/b antenna as a solution.
This antenna covers GPS, GLONASS and Galileo bands and is available in two different modifications, tuned for no groundplane (suffix „a“) and tuned for groundplane(suffix „b“). It gives more flexibility for designers – the same antenna could be used for handheld devices or for fixed units, used e.g. in cars or bicycles. Antenna has an SMA connector embedded, which makes connection to the application very convenient. Embedded LNA has 24db gain at 3V and even higher 25db at 5V. Very low WSVR <1.2:1 assures high quality signal level and short TTFFs. Wide operating temperature range -40°C.....+85°C is standard for industrial applications.
