Molex high-performance standard antenna solutions


Based on diverse manufacturing and RF technologies, Molex standard antennas offer high performance and ease of integration for demanding wireless applications spanning the industrial, consumer, medical and automotive markets

With multiple markets trending toward wireless applications, many wireless devices are better served with a standard antenna rather than a customized one. Molex standard antennas deliver superior performance for less cost and risk—and shortened lead times for bringing wireless products to market.

The current selection of Molex standard antennas are designed for M2M communication over the ISM (industrial, scientific and medical) bands and cellular bands (including GSM850, GSM900, GSM1800, GSM1900, UMTS [3G] band-1 and LTE band-7), as well as applications running Wi-Fi* and mobile TV (DVB-H and CMMB). Major OEMs and ODMs around the world have chosen Molex to support a wide range of communication technologies including cellular, UMTS, Wi-Fi*, WIMAX, Bluetooth, GPS, and others.

Our technical experts work through all projects phases with our customers to determine cost-effective ways of designing wireless antenna solutions while ensuring quick time-to-market. Molex uses the state-of-the-art technology, and a combination of its latest patented technologies, lean manufacturing techniques, custom automation and vertical integration to deliver products of the highest quality, reliability and performance.


Multi-band Cellular and Combo Cellular/Wi-Fi* Flexible Antennas with Balanced Transmission Advanced Flexible Antenna Technology 

Combine extended cellular coverage with Wi-Fi capabilities for better connectivity and faster wireless-device processing. This balanced combo antenna with ground-plane independent design, reduces engineering resources and costs needed to mitigate PCB ground-induced radiation. High radiation efficiencies support high-performance RF application needs. Poly-flexible, double-sided adhesive tape on antenna enables easy peel-and-stick mounting anywhere within the device casing.

2.4 GHz Surface Mount Device (SMD) On-ground Antenna


Developed with the power and precision of Laser Direct Structuring (LDS) technology, Molex’s 2.4 GHz SMD on-ground antenna is the smallest on-ground MID (Molded Interconnect Device) antenna in the market. The lightweight Molded Interconnect Device (MID) chip antenna weighs only 0.03g and is used in portable electronic devices based on Bluetooth, Wi-Fi*, ZIGBEE and other wireless standards. Measuring only 3.00mm by 3.00mm by 4.00mm (0.118" by 0.118" by 0.157") and used on one side of the PCB, the antenna allows board makers to realize significant PCB real estate savings by leaving the ground layers in the PCB intact while freeing up space on the reverse side of the PCB for other component assemblies.

2.4/5GHz Wi-Fi* Flexible Antenna with Balanced Transmission, RoHS-compliant, Halogen-free


Dual-band transmission-balanced antennas combine ground-plane independence with high-radiation efficiency for better connectivity and faster wireless device processing. Balanced antenna with ground-plane independent design reduces engineering resources and costs needed to mitigate PCB ground-induced radiation. High radiation efficiency with 34.90 by 9.00mm strip antenna offers total efficiency values of 75% minimum in the 2.4GHz band and 70% minimum in the 5GHz band. Poly-flexible, double-sided adhesive tape on antenna enables easy peel-and-stick mounting anywhere within the device casing.

MCX RF connectors


The MCX RF connectors are designed for use in any wire-to-board application where quick and easy snap-on mating is needed. Available in 50 and 75 Ohm and frequencies up to 6 GHz, the MCX subminiature snap-on connectors offer a stable and durable connection. The subminiature design allows other electronic assemblies to be densely packaged on the PCB. MCX connectors are approximately 30% smaller than SMB connectors, and are available in both 50 and 75 Ohm versions and provide good electrical performance to 6 GHz. These connectors are used in telecommunications systems as well as wireless and GPS applications. For medical MRI applications, non-magnetic versions are available. Molex also provides multi-port MCX connectors for coplanar board-to-board and cable-to-board applications.

FAKRA II SMB connector system


FAKRA II SMB connectors, with 360° rotation and secondary locking latch deliver easy cable routing between antennas and multi-media units while meeting the USCAR requirements for on-board telematics systems’ Molex’s FAKRA II SMB product offering meets both American USCAR and German FAKRA automotive standards.
