The base 35 x 35mm patch and the upper 25 x25mm patch have a single pin feed output that combines both L1 and L2 signals into one to simplify the overall design of the device receiver which lowers power consumption, saves on the number of electronic components which in turn saves on costs and reduces PCB space. At just 6mm in height it is a great option for devices requiring a compact multiband GNSS patch. The GPSF356.A exhibits very good gain and radiation pattern stability on both L1 and L2 bands, improved reliability of a GPS fix in urban areas, better receive signal reception with more satellites acquired, and a quicker time to first fix. Typical applications include: - High accuracy positioning and navigation systems - UAVs, Robotics & Autonomous Vehicles - Mapping & GIS - Transportation & Telematics - Precision Agriculture - Public Safety, Search & Rescue - RTK Systems This patch is tuned specifically for a 70*70mm ground plane however patch antennas can also be tuned to customer-specific device environments, subject to NRE and MOQ. If active electronics are required, the GPSF356.A can be combined with the Taoglas TFM.100A GNSS Front End Module that features a SAW/LNA/SAW/LNA topology in both the low and high band signal paths to prevent unwanted out-of-band interference from overdriving the GNSS LNAs or receiver. Including the active. Contact your regional Taoglas customer support team to request these services or additional support to integrate and test this antenna’s performance in your device. 3 www.taoglas.com SPE-24-8-234-A |**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**| |---|---|---|---|---|---| |**GPS**|**L1**<br>**1575.42 MHz**|**L2**<br>**1227.6 MHz**|**L5**<br>**1176.45 MHz**||| ||◼|◼|||| |**GLONASS**|**G1**<br>**1602 MHz**|**G2**<br>**1248 MHz**|**G3**<br>**1207 MHz**||| ||◼||||| |**Galileo**|**E1**<br>**1575.24 MHz**|**E5a**<br>**1176.45 MHz**|**E5b**<br>**1201.5 MHz**|**E6**<br>**1278.75 MHz**|| ||◼||||| |**BeiDou**|**B1C**<br>**1575.42 MHz**|**B1I**<br>**1561 MHz**|**B2a**<br>**1176.45 MHz**|**B2b**<br>**1207.14 MHz**|**B3**<br>**1268.52 MHz**| ||◼|◼|||| |**L-Band**|**L-Band**<br>**1542 MHz**||||| ||◼||||| |**QZSS (Regional)**|**L1**<br>**1575.42 MHz**|**L2C**<br>**1227.6 MHz**|**L5**<br>**1176.45 MHz**|**L6**<br>**1278.75e6**|| ||◼|◼|||| |**IRNSS (Regional)**|**L5**<br>**1176.45 MHz**||||| ||||||| |**SBAS**|**L1/E1/B1**<br>**1575.42 MHz**|**L5/B2a/E5a**<br>**1176.45 MHz**|**G1**<br>**1602 MHz**|**G2**<br>**1248 MHz**|**G3**<br>**1207 MHz**| ||◼||◼||| ## GNSS Bands and Constellations 4 www.taoglas.com SPE-24-8-234-A |||||| |---|---|---|---|---| ||**GNSS Electrical**|||| |||||| |||||| |**Frequency (MHz)**|**1227.6**|**1561**|**1575.42**|**1603**| |||||| |||||| |**VSWR (max.)**|4:1|2:1|2:1|2:1| |||||| |**Passive Antenna**||||| ||56.11|79.3|67.16|63.57| |**Efficiency (%)**||||| |||||| |**Passive Antenna Gain at**||||| ||3.54|3.02|3.19|3.19| |**Zenith (dBic)**||||| |||||| |||||| |**Axial Ratio (dB)**|9.03|17.09|11.49|11.96| |||||| |||||| |**Polarization**|RHCP|||| |||||| |||||| |**Impedance**|50 Ω|||| |||||| ||**Mechanical**| |---|---| ||| |**Dimensions**|35 x 35 x 6.12mm| ||| ||| |**Weight**|20g| ||| ||| |**Material**|Ceramic| ||| ||| |**Pin Length**|2.4mm| ||| ||**Environmental**| |---|---| ||| |**Operation Temperature**|-40°C to 85°C| ||| ||| |**Storage Temperature**|-40°C to 85°C| ||| ||| |**Relative Humidity**|Non-condensing 65°C 95% RH| ||| 5 www.taoglas.com SPE-24-8-234-A 6 www.taoglas.com SPE-24-8-234-A 12pc per tray 6 Trays per vacuum package 2 pcs desiccant 3g 72pcs per box Box dimensions: 261 x 15 x 118mm Weight: 1.9Kg 288pcs per carton Carton dimensions: 330 x 280 x 270mm Weight: 8.1Kg 7 www.taoglas.com SPE-24-8-234-A ## Test Setup VNA Test Setup on a 70 x 70mm Ground Plane 8 www.taoglas.com SPE-24-8-234-A ## Return Loss ## VSWR 9 www.taoglas.com SPE-24-8-234-A ## Efficiency ## Average Gain 10 www.taoglas.com SPE-24-8-234-A ## Peak Gain ## Axial Ratio 11 www.taoglas.com SPE-24-8-234-A ## Test Setup **==> picture [63 x 75] intentionally omitted <==** **----- Start of picture text -----**<br> Y<br>X<br>Z<br>**----- End of picture text -----**<br> Chamber Test Set-up on a 70 x 70mm Ground Plane 12 www.taoglas.com SPE-24-8-234-A ## Patterns at 1228 MHz ## XZ Plane ## YZ Plane ## XY Plane 13 www.taoglas.com SPE-24-8-234-A ## Patterns at 1562 MHz ## XZ Plane ## YZ Plane ## XY Plane 14 www.taoglas.com SPE-24-8-234-A ## Patterns at 1575 MHz ## XZ Plane ## YZ Plane **==> picture [44 x 10] intentionally omitted <==** **----- Start of picture text -----**<br> XY Plane<br>**----- End of picture text -----**<br> 15 www.taoglas.com SPE-24-8-234-A ## Patterns at 1602 MHz ## XZ Plane ## YZ Plane ## XY Plane 16 www.taoglas.com SPE-24-8-234-A Changelog for the datasheet **SPE-24-8-234 – GPSFB356.A Revision: A (Initial Release)** Date: 2024-09-24 Notes: Initial Datasheet Release Author: Gary West ## **Previous Revisions** **==> picture [495 x 480] intentionally omitted <==** 17 www.taoglas.com SPE-24-8-234-A 18 www.taoglas.com SPE-24-8-234-A
