Antenna Description

Bringing the Most Compact, Most Advanced GPS Precision Technology to the Global Navigational Platform

With a footprint of 25x25x12 mm only,  The 2JM3201C3F is the most compact, high precision, low profile internal ceramic active stacked patch antenna with L1 and L5 bands on the market. 2JM3201C3F offers reliability, greater bandwidth, and high gain by combining concurrent reception on GPS L1 and L5 bands to all global/regional/SBAS navigation satellite systems (GPS, BeiDou, GLONASS, Galileo, QZSS and IRNSS). The L5 band is the most advanced GNSS signal on the market and gives military-grade GPS accuracy to users worldwide while enabling the usage of dead reckoning process.  By combining Precise Point Positioning (PPP) of L1 and L5  with the Indian Regional Navigation Satellite System (IRNSS), this antenna is the ideal choice for GNSS surveying applications where high precision is needed, such as the obstructed environment of tree lines or construction. With the SBAS Satellite-based Augmentation system, this antenna effectively improves measurement accuracy and provides better positioning solutions.

 

 Typical applications include:

  • Aviation Safety
  • Safety-Critical Systems & Transportation
  • Autonomous Vehicles
  • Agriculture
  • Navigation
  • Wearables

This antenna works on single feed technology. With low power consumption and a wide voltage range, it is a perfect choice for multiple applications. It has high efficiency within 1176 MHz (L5) and 1561-1606 MHz (L1) frequencies with an active gain of 28dB. It gives strong anti-interference performance due to low noise figures. It has a high rejection pre-filter due to which it effectively avoids disconnection when receivers are operated under complex electromagnetic environments such as communication base station applications or urban areas. 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 2JM3201C3F offers low noise figures of 1.6 dB at 3V, ESD 2kV protection.

 

This antenna is also available in other configurations including RTK/L1L2 (2JM3201C2F) and IRNSS/L1L2L5 (2JM3201C5F).

Installation / Environmental

This small form factor antenna provides an easy installation via a practical snap-in mount module.  Both patches are manufactured from a durable ceramic material, offering durability in temperatures ranging between -40C to +85C. It is a ground plane independent design, which allows it to be installed securely on a wide range of surfaces without restrictions. The 2JM3201C3F 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. 2J Antennas supports the health of our environment and manufactures all our products without hazardous materials making us fully REACH and RoHS compliant.
