DSP-15-8-SPE-17-8-028/A/SS Page 1 of 17 SPECIFICATION Description : GPS L1 / GALILEO E1 1575MHz 12*12*4mm Ceramic Patch SMT Antenna Features : 2.73 dBi Peak Gain for GPS/GALILEO Band Dims: 12*12*4mm SMT Direct Mount Ceramic Patch Antenna Automotive TS16949 Approved RoHS compliant
DSP-15-8-SPE-17-8-028/A/SS Page 2 of 17 1. Introduction 12mm square and with a height of just 4mm, this antenna is perfect for applications in compact telematics devices, vehicle tracking/fleet management systems, wearables and navigation devices. The antenna has been tuned on a 50* 50mm ground plane, working at 1575.42MHz with a 2.73dBi gain. The ceramic patch is mounted via SMT process, suitable for high volume low cost assembly. The antenna is manufactured and tested in a TS16949 first tier automotive approved facility. Small antennas should ideally be custom tuned for the device environment , Taoglas offers this service subject to NRE and MOQ . For more details please contact your regional Taoglas sales office.
