Antenna Description

High-Precision Navigation With The Most Compact Antenna on The Market 

The multi-band GPS/GLONASS L1/L2/RTK stacked ceramic patch antenna measures only 25x25x8 mm and is the most compact on the market. This revolutionary design offers concurrent reception on GLONASS, BeiDou, Galileo, QZSS, SBAS, RTK and L1 L2 and allows for superior precision and advanced navigation while enabling the usage of dead reckoning process.  By combining Precise Point Positioning (PPP) of L1 and L2 with Real-Time Kinematic (RTK) satellite navigation, this solution is the ideal choice for applications such as land and hydrographic survey applications. With SBAS Satellite-based Augmentation system, it detects correction errors, positioning errors, which makes it a perfect fit for safety-critical applications too.

 Typical applications include:

  • Navigation
  • Aviation Safety
  •  Unmanned Aerial Vehicle Navigation
  •  Civil Aviation boosting the receiver signal
  • Safety-Critical Systems & Transportation
  • Autonomous Vehicles
  •  Agriculture
  •  Land Survey
  • Hydrographic Survey

This antenna works on single feed technology. With low power consumption and a wide voltage range, this antenna is a perfect choice for multiple applications. It has high efficiency within 1227 MHz (L2) and 1561-1606 MHz (L1) frequencies. It has a high rejection pre-filter without compromising on active gains that are 28 dB at 3V. It provides real-time error corrections while simultaneously maintaining centimeter precise position data throughput when passing through solid objects or high coverage landscapes. This antenna is right-handed circular polarization (RHCP) which makes it perfect to reject multipath fading and interference thus improving the signal strength. The 2JM3201C2F offers low noise figures of 1.6 dB at 3V and ESD 2kV protection.

This antenna is also available in other configurations including IRNSS/L1L5 (2JM3201C3F) and IRNSS/L1L2L5 (2JM3201C5F).

Installation / Environmental

This ultra low profile antenna solution features an easy installation via snap-in mount module. The 2JM3201C2F is a compact ceramic antenna manufactured without any hazardous materials and is both REACH and RoHS compliant and durable in temperatures ranging between -40C and +85C. It is a ground plane independent design, which allows it to be installed securely on a wide range of surfaces without restrictions. The 2JM3201C2F is delivered with a standard U.FL connector and a 100 mm long mini coax standard cable. It is fully customizable by offering additional connector types, cable lengths, and cable types.
