Introduction The Taoglas Accura GVLB258.A, is a multi-band GPS, BeiDou/Compass and IRNSS, high-performance directional antenna for high precision GPS and BeiDou accuracy and fast positioning. It utilizes a 25*25*8mm advanced wide-band dual stacked ceramic patch antenna with optimized gain for GPS L1/L5, Galileo, GLONASS and BeiDou bands. Typical Applications Include: - RTK - Wearables - Transportation - Agriculture - Navigation - Security - Autonomous Vehicles The GVLB258.A has been tuned and tested on a 70 x 70 mm ground plane and exhibits excellent radiation patterns. The GVLB258.A has been optimised to cover the bands required for the next generation of L1/L5 GNSS receivers that are currently on the market. Patch antennas can be specifically tuned to customer-specific device environments, subject to NRE and MOQ. 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. www.taoglas.com 3 SPE-21-8-082-A ## **2.** Specifications |**GNSS Frequency Bands Covered**|**GNSS Frequency Bands Covered**|**GNSS Frequency Bands Covered**|**GNSS Frequency Bands Covered**|**GNSS Frequency Bands Covered**|**GNSS Frequency Bands Covered**|**GNSS Frequency Bands Covered**| |---|---|---|---|---|---|---| |**GPS**|L1|L2|L5|||| ||▓|□|▓|||| |**GLONASS**|G1|G2|G3|||| ||▓|□|□|||| |**Galileo**|E1|E5a|E5b|E6||| ||▓|▓|□|□||| |**BeiDou**|B1|B2a|B2b|B3||| ||▓|□|□|□||| |**QZSS**<br>**(Regional)**|L1|L2C|L5|L6||| ||▓|□|▓|□||| |**IRNSS**<br>**(Regional)**|L5|||||| ||▓|||||| |**SBAS**|L1/E1/B1|L5/B2a/E5a|G1|G2|G3|| ||▓|▓|▓|□|□|| ◼ GNSS Frequency Bands Covered. □ GNSS Frequency Bands Not Covered. *SBAS systems: WASS(L1/L5), EGNOSS(E1/E5a), SDCM(G1/G2/G3), SNAS(B1,B2a), GAGAN(L1/L5), QZSS(L1/L5), KAZZ(L1/L5). ## GNSS Bands and Constellations www.taoglas.com SPE-21-8-082-A 4 ||**Electrical**|**Electrical**|**Electrical**|**Electrical**| |---|---|---|---|---| |**Frequency (MHz)**|**GPS L5 / GLONASS E5a /**<br>**IRNSS L5 / BeiDou B2a**|**BeiDou B1**|**GPS L1 / Galileo E1**|**GLONASS G1**| ||**1166-1186**|**1559-1563**|**1563-1587**|**1593-1610**| |Efficiency (%)|58.5|68.5|60.7|62.5| |Peak Gain(dBi)|2.31|2.94|2.87|3.08| |Average Gain(dB)|-2.33|-1.64|-2.17|-2.04| |Polarization|R.H.C.P.|||| |Radiation Pattern|Omni|||| |Impedance|50 Ω|||| ||**Mechanical**| |---|---| |Planner Dimension|25*25*8mm| |Ground Plane|70*70mm| |Connection Type|Pin & Adhesive Mount| ||**Environmental**| |Temperature Range|-40°C to 85°C| |Humidity|Non-condensing 65°C 95% RH| www.taoglas.com 5 SPE-21-8-082-A ## **3.** Antenna Characteristics **==> picture [479 x 301] intentionally omitted <==** **----- Start of picture text -----**<br> 3.1 Return Loss<br>0<br>-6<br>1169MHz@-6dB to 1551MHz@-6dB to L1+L5 Band<br>-12 1185MHz@-6dB 1604MHz@-6dB<br>-18<br>-24<br>-30<br>1100 1150 1200 1250 1300 1350 1400 1450 1500 1550 1600 1650 1700<br>(MHz)<br>(Return loss)<br>**----- End of picture text -----**<br> ## **3.2** Efficiency www.taoglas.com 6 SPE-21-8-082-A ## **3.3** Average Gain ## **3.4** Peak Gain www.taoglas.com SPE-21-8-082-A 7 ## **3.5** Axial Ratio – X-Z 4 **==> picture [419 x 374] intentionally omitted <==** **----- Start of picture text -----**<br> 20.0<br>SRE 1 eee eee Ce ee De)<br>18.0 ee | ee ee ee )<br>ee ieee eee ee)<br>16.0 8eses ||IRRRee(Reeieee)|)<br>14.0 |<br>|(Ree)<br>es Eee)<br>ee<br>12.0 ee | Pee eeeee)<br>ee [(eee] eee| |<br>10.0<br>Ieee)<br>ee) | |<br>8.0 ee) |<br>eeee) PeeIeee) [Ieee)] eee)<br>6.0<br>eeee (eee)Ieee)|)<br>4.0<br>eeee (eee)Ieee)|)<br>2.0<br>eeee (eee)Ieee)|)<br>0.0 |)<br>1.10 1.15 1.20 1.25 1.30 1.35 1.40 1.45 1.50 1.55 1.60 1.65<br>Frequency [GHz]<br>GVLB258.A<br>**----- End of picture text -----**<br> www.taoglas.com 8 SPE-21-8-082-A ## **4.** Radiation Patterns **4.** **==> picture [106 x 12] intentionally omitted <==** **----- Start of picture text -----**<br> 4.1 Test Setup<br>**----- End of picture text -----**<br> **==> picture [73 x 97] intentionally omitted <==** **----- Start of picture text -----**<br> Z<br>X<br>Y<br>**----- End of picture text -----**<br> Tested on 70*70mm Ground Plane Evaluation Board www.taoglas.com SPE-21-8-082-A 9 ## **4.2** 2D Radiation Patterns ## 1176MHz ## XY Plane ## XZ Plane ## YZ Plane www.taoglas.com 10 SPE-21-8-082-A ## 1561MHz ## XY Plane ## XZ Plane ## YZ Plane www.taoglas.com 11 SPE-21-8-082-A ## 1575MHz ## XY Plane ## XZ Plane ## YZ Plane www.taoglas.com 12 SPE-21-8-082-A ## 1602MHz ## XY Plane ## XZ Plane ## YZ Plane www.taoglas.com 13 SPE-21-8-082-A ## **5.** Mechanical Drawing (Units: mm) www.taoglas.com 14 SPE-21-8-082-A **6.** Footprint www.taoglas.com 15 SPE-21-8-082-A ## **7.** Packaging 24pcs GVLB258.A per Tray Tray Dimensions: 255*144*8mm Weight: 0.460Kg 96pcs GVLB258.A per Inner Carton Dimensions: 263*154*96mm Weight: 2Kg 384pcs GVLB258.A per Large Carton Dimensions: 327*280*218mm Weight: 9Kg www.taoglas.com 16 SPE-21-8-082-A Changelog for the datasheet **SPE-21-8-082 – GVLB258.A** ## **Revision: A (Original First Release)** Date: 2021-09-06 Notes: Initial Release Author: Jack Conroy ## **Previous Revisions** **==> picture [495 x 480] intentionally omitted <==** www.taoglas.com 17 SPE-21-8-082-A www.taoglas.com © Taoglas www.taoglas.com SPE-21-8-082-A 18

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
