1. Introduction
The GPSDSF.35.7.A.08 is a passive 35x35mm ceramic stacked patch antenna with
both SDARS and GNSS capabilities. This patch provides world-class performance for
both SDARS and GNSS services, with AR GPS:5.0 dB typ, GLONASS: 7.5 dB typ.
SDARS(XM): 3.8 dB typ right hand circular polarization and nearly 70% efficiency at
2332.5 MHz for SDARS and 70-80% efficiency at GPS/GLONASS/GALILEO frequencies.
Using one patch for both services results in the most economical and space-efficient
solution for demanding applications requiring both SDARS and GNSS functionality. At
just 7.15 mm in height, the GPSDSF.35 is also extremely low-profile.
Typical Applications:
• OEM Sharkfin Automotive Antennas
• Truck Mounted Antenna Systems
This antenna has been tuned and tested on a 70 x 70 mm ground plane. Custom
tuning services can be provided for further optimization to customer-specific device
environments. Contact your regional Taoglas sales office for support.
