On-ground chip antenna

27 January 2016 Telecoms, Datacoms, Wireless, IoT

Molex’s 2,4 GHz SMD antenna, model number 47948, requires no ground clearance and offers significant PCB real-estate savings.

Developed with the power and precision of laser direct structuring (LDS) technology, this lightweight chip antenna weighs only 0,03 g and is ideal for portable electronic devices based on Bluetooth, Wi-Fi, ZigBee and other wireless standards.

The monopole antenna has an omnidirectional 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 standalone 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.

Measuring only 3 x 3 x 4 mm and used on one side of the PCB, the antenna allows board makers to realise significant PCB real estate savings by leaving the ground layers in the PCB intact while freeing up space on the reverse side of the board for other component assemblies.
