Rugged, Compact Multi-Band Antenna for L1, L5, and Critical S-Band Applications

Drawing on two decades of specialized knowledge in high-performance GNSS solutions at Xtragen Technologies Pvt. Ltd., I introduce the advanced Model No. XT-GNSS-IGATBV3-21. This antenna is meticulously engineered and proudly MADE IN INDIA to provide low-noise coverage across the entire GNSS frequency range, including the standard bands and the critical IRNSS S-Band.

This product is highly versatile, offering simultaneous multi-band coverage in a durable, compact, and lightweight form factor. It is ideal for vehicular, marine, and field applications that require high precision and broad spectral coverage.

Key Technical Advantages & Features:

• IRNSS Quad-Band Application: Provides comprehensive signal reception, crucially including the high-frequency S-Band alongside the L-Bands.

  • L5 Band: IRNSS L5, GPS L5, E5a, SBAS L5, QZSS L5 (≈1176.45±20 MHz)

  • L1 Band: GPS L1, B1, E1, SBAS L1, QZSS L1 (≈1575.42±40 MHz)

  • S Band: IRNSS S (≈2492±20 MHz)

• Superior RF Performance:

  • High Gain: Achieves strong gains of 4.0 dBic (L5), 5.2 dBic (L1), and 5.6 dBic (S-Band) at zenith.

  • Low Noise Figure: Features an excellent Noise Figure of ≤2.5 dB (L1/L5) and ≤2.8 dB (S-Band).

  • Robust Filtering: Provides efficient suppression of out-of-band interferences with an Out-of-band Rejection of >40 dB.

• High Precision: Offers superior signal quality with a stable Phase Centre accuracy of ±2 mm, vital for applications requiring high position repeatability.

• Compact & Rugged Mechanical Specifications: Built to withstand demanding conditions:

  • Dimensions: Compact size of 115×115×37 mm for easy integration.

  • Lightweight: Weighs less than 0.3 KG (<0.3 KG).

  • Connector: Reliable SMA (F) Connector.

  • Power: Operates efficiently on 5V/ 180 mA DC power.

  • Extreme Operating Range: Functions reliably across extreme temperatures from −40∘C to 85∘C.

• Multipath Mitigation: High rejection capability (>20 dB) and good axial ratio (1.2 dB to 1.5 dB) minimize signal reflection interference, ensuring clean data.

The XT-GNSS-IGATBV3-21 is the ideal compact solution for applications requiring reliable access to the IRNSS S-Band signal in conjunction with standard GNSS frequencies.
