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.

These devices include tablet PCs, headsets, smart meters and more. 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.

This monopole antenna has an omni-directional radiation pattern and requires only simple stripline matching on the PCB, without the need for discrete components. It is fully compatible with SMD and reflow processes and usable as a stand-alone device without the need for cable connection. Besides offering good thermal properties, the LCP body of the antenna provides a higher mechanical strain tolerance than ceramic ones.

Feature and Benefits

• Valuable PCB real estate savings on both sides of the PCB with the use of this miniature antenna
• No removal of ground layers from beneath the antenna is needed
• Consistent antenna RF performance with the application of Laser Direct Structuring (LDS) - a technology known for its excellent precision, performance and repeatability
• The high-temperature base material and the metal plating technology employed allows the antenna to endure reflow temperatures - an ideal condition for a standard SMT process
• The product is halogen-free and RoHS-compliant

Product Feature

In the left diagram below, four SMD pads are shown. Three dummy pads are to be attached to the PCB for strong mechanical bonding while the remaining signal SMD pad connects to the radio transceiver circuit on the PCB

In the right diagram below, the pick-and-place feature of the antenna works with a standard vacuum nozzle for component assembly operations
