SPECIFICATION Part No. : CGIP.25.4.A.02 Product Name : 25mm Iridium® / GPS Ceramic Patch Antenna 1575–1626MHz Single Feed Feature : Wide Operation Band High Gain Dims:25*25*4mm Single feed ceramic patch for combined Iridium®/GPS applications Iridium® has certified the CGIP.25.4.A.02 antenna for commercial use connection with the in Iridium® Communications System RoHS Compliant SPE-11-8-132/H/WY Page 1 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 performance in the 1575.42 to 1626.5MHz 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, as 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 performance on a device is a function of the overall system design of the device and environment where the device is used. Use of even a tuned patch or any antenna on a compromised device design or application will not guarantee good GPS/Iridium® performance. SPE-11-8-132/H/WY Page 2 of 18 2.

CGIP.25.4.A.02 on Evaluation Board The CGIP.25.4.A.02 is designed with 70*70mm square metal plane, put the antenna at the center of the metal ground, and then the antenna will have excellent performance. The recommendation setup is shown as follows. SPE-11-8-132/H/WY Page 13 of 18 7. PCB Layout Recommendation *The antenna feeding in transmission line should connect with theφ2.5 circle at the Bottom Side, and keep transmission line impedance at 50 ohms for good power transmit from system to antenna.
