s pe - 11 - 8 - 132/ h /wy page 1 of 18 specification part no. : cgip.25.4.a.02 product name : 25mm iridium ? / gps ceramic patch antenna 1 575 C
s pe - 11 - 8 - 132/ h /wy page 2 of 18 1. introduction the taoglas gps/iridium ? cgip.25 ceramic patch antenna is a low profile (4mm) , small footprint (25 *25mm) , single feed antenna designed for combined iridium ? /gps applications . it has been specifically designed to provide excellent performanc e in the 1575.42 to 1626.5 mhz range. this ceramic patch offers a typical peak gain of 5dbi for gps and iridium ? . these patches are mounted via pin and double - sided adhesive. while the antenna is certified, some antenna detuning or device or layout issues* may prevent a device from passing iridium ? certification. taoglas offers performance testing and verification, a s well as a custom tuning service for the patch for a specific customer device and ground - plane mounting. taoglas can also pre - test the whole device for iridium ? certification. please contact us for any assistance required. *actual gps/iridium ? system perf ormance on a device is a function of the overall system de sign of the device and environment where the device is used . u se of even a tuned patch or any antenna on a compromised device design or application will not guarantee good gps/iridium ? performance.
