SPECIFICATION Part No. : CGGBP.35.3.A.02 Product Name : 35mm*35mm*3mm 4dBi+ GPS/GLONASS/BEIDOU Ceramic Patch Antenna Features : Stable gain on all three GNSS applications Excellent radiation pattern coverage Dielectric Ceramic Pin (Through hole) Mount RoHS Compliant SPE-15-8-010/A/SS Page 1 of 14 1. Introduction This CGGBP.35 35mm*35mm embedded ceramic GPS/GLONASS/BEIDOU patch antenna has a wide band of operation, leading to excellent gain and radiation pattern stability on all three GNSS system bands. Compared to using a smaller antenna, this will translate into the GNSS system having much higher location accuracy, improved reliability of lock in urban areas, better signal reception, with more satellites acquired and a quicker time to first fix. The patch is mounted via pin and double-sided adhesive. While the antenna will work very well in most device environments (Note cannot be covered with metal enclosure), tuning and further optimization of this antenna to different ground-planes and enclosures can be done if required, also including a pin length change. These changes would be subject to possible NRE and a minimum order quantity. Contact your local Taoglas sales office for more details. SPE-15-8-010/A/SS Page 2 of 14 2.
