Molex 211624 series GNSS/GPS antennas

GNSS/GPS-enabled devices need highly compact antennas with high radiation efficiency performance. Measuring only 3.20 by 1.60 by 1.10mm, Molex Low-Profile GNSS Ceramic Antennas offer maximum space savings with an average total radiation efficiency of at least 60% over 1561 to 1602 MHz bands.

Some applications require zero-PCB-clearance zone and high radiation efficiencies of no less than 70%. They must also support a wide operating temperature range. Molex GPS/BEIDOU/GLONASS Ceramic Antennas have an average total radiation efficiency of greater than 70% at the 1561 and 1571 MHz bands, and greater than 75% at the 1602 MHz band. This 25.00-by-25.00mm patch antenna operates from -40 to +125°C.

Navigation-based applications that use linearly polarized antennas often encounter signal propagation anomalies and ground reflections. Molex Circular or Elliptically Polarized Antennas overcome effects of signal propagation anomalies and ground reflections specific to linearly polarized antennas.

Features

• Feeding pad
  • Connects to the radio transceiver via a 50-Ohm transmission line on the PCB
  • Electrical signals from the transmission line are fed through this pad on the PCB
• Antenna Radiator (Low-Profile GNSS)
  • Acts as a transducer to convert unguided electromagnetic waves to guided electromagnetic waves and vice versa
• Ceramic Patch Antenna (GPS/BEIDOU/GLONASS)
  • Delivers high gain, high radiation efficiency performance for the most demanding GPS applications
• RHCP version offers horizontal Plan of PCB (GPS/BEIDOU/GLONASS)
  • Helps ensure highest gain from antenna
  • Patch antenna achieves highest gain when place horizontally on a surface facing the z-axis since it can receive all propagated GPS signals
  • Lower gain will be experienced if the patch antenna is mounted on a surface that makes an angle with the horizontal
• Pick-and-place feature (RHCP/Helix SMT LDS-MID GPS Antenna)
  • Speeds up automated placement of antenna during assembly
• Feeding pad (RHCP/Helix SMT LDS-MID GPS Antenna)
  • Connects to the radio transceiver via a 50-Ohm transmission line on the PCB
  • Electrical signals from the transmission line are fed through this pad on the PCB
• Ceramic Antenna Housing (Low-Profile GNSS)
  • Compact, inexpensive and easy to integrate into applications subject to high reflow temperatures
• Feeding pad (double-sided adhesive) (GPS/BEIDOU/GLONASS)
  • Secures the antenna to the PCB
• Silver Pin (GPS/BEIDOU/GLONASS)
  • Positions and fixes the antenna to the PCB (via soldering)
  • Provides electrical contact between antenna and board
• Laser Direct Structuring (LDS)-formed antenna radiator (RHCP/Helix SMT LDS-MID GPS Antenna)
  • Yield high, consistent RF performance, leveraging the excellent laser structuring precision, speed, accuracy and repeatability of LDS technology
• Gold (Au) over Nickel (Ni) traces (RHCP/Helix SMT LDS-MID GPS Antenna)
  • Acts as transducers that convert unguided electromagnetic waves to guided electromagnetic waves and vice versa
