Molex LDS-MID and Ceramic GPS Antennas
The Molex Ceramic and LDS-MID GPS Antenna eradicate space and PCB real-estate constraints. LDS-MID and Ceramic GPS antennas combine ease of integration over a variety of wireless navigation device applications. GNSS active patch and flexible antennas complement ceramic and LDS-MID chip selections for superior signal processing and ground independence over a wide range of navigation and tracking applications. The mid-tech GPS connects to the radio transceiver via a 50Ω transmission line on the PCB. Molex GPS antenna yields high, consistent RF performance, leveraging the excellent laser structuring precision, speed, accuracy, and repeatability of LDS technology.
The series 206640 active antenna with a low-noise amplifier offers better signal performance (lower noise) and is slimmer (6.50mm) than its competing equivalent. The Series 206560 antenna is ground-plane independent and is balanced throughout the antenna regardless of cable lengths. Customers have 6 cable length options to choose from for maximum design flexibility.
Features
- Double-sided adhesive liner enables easy peel-and-stick operations on the PCB
- Feeding pad (double-sided adhesive) secures the antenna to the PCB
- Horizontal plane of PCB helps ensure highest gain from the antenna
- Silver pin position and fixes the antenna to the PCB
- The LDS antenna has Gold (Au) over Nickel (Ni) traces:
- Acts as transducers that convert unguided electromagnetic waves to guided electromagnetic waves and vice versa.
Applications
- Automotive
- Commercial aviation
- Commercial vehicle:
- Agricultural vehicle
- Rail
- Consumer (Recreational):
- Geocaching
- Industrial:
- Emergency response systems
- Maritime port management system
- Surveying and mapping systems

Look, some people have a hard time asking for directions, which is what makes GNSS systems like GPS so great, but sometimes RF design can be harder than asking for directions, and new applications require designers to fit more functionality into less space at a lower cost and in a shorter time. That's why Molex offers a portfolio of ceramic and LDS-MID GNSS antennas that eliminate space and PCB real-estate constraints, reduce implementation costs, and can be easily integrated with minimal RF expertise.
Antennas are available for use with various satellite systems and to meet different application requirements including antennas with no PCB clearance requirement SMT enabled low profile, and multiple options for antenna type and polarization. Molex GNSS antennas are easily tuned and can be used in applications ranging from consumer wearables to commercial aviation and industrial applications.
