Molex 2.4/5-GHz and 900-MHz ultra-thin Ceramic and LDS/MID Antennas

Internet of Things (IoT) Antennas: Wi-Fi, Bluetooth, Zigbee

2.4/5-GHz and 900-MHz ultra-thin Ceramic and LDS/MID antennas from Molex offer cabled, flex and PCB formats to enable fast and easy RF integration into connected systems and are ideal for embedding high-performing internet and data connectivity in compact devices.

Compact, efficient, high-gain antennas, combined with massive expansions of wireless and data networks, have changed the ways that devices are designed and developed. The external antenna has given way to PCB and internally cabled antennas in practically all of today’s connected devices. In response, Molex Antenna Products provide many choices to designers of wireless-enabled devices that support one or more protocols, including Bluetooth, Wi-Fi, Zigbee and WLAN. Molex also offers antennas in various form factors, such as SMD mounting, internally cabled PCB antennas as well as cabled internal adhesive antennas. They support maximum radiation efficiencies over a wide range of wireless applications, delivering unmatched performance.

Molex PCB antennas are ideal for modern pick-and-place manufacturing technologies. To facilitate the most optimal design of PCB antennas, Molex has published application specifications that provide easy-to-understand antenna design guidelines.Molex Flexible Antennas

For applications where an internally cabled antenna is preferred, Molex offers two types: one fabricated from a PCB and the other with a flexible, adhesive-backed surface for convenient mounting inside the device. Furthermore, cable length options of 50.00 to 300.00mm provide extended connectivity and balanced transmission throughout, from antenna to UFL connector. Application specifications are also published for Molex cabled antennas.
