2,4 / 5 GHz antennas

29 October 2014 Telecoms, Datacoms, Wireless, IoT

Molex’s range of 2,4 / 5 GHz standalone antennas combine ground-plane-independent design with high radiation efficiency.

Series 47950 antennas include the small footprint 34,5 by 9,00 mm version that delivers 75% minimum total efficiency in the 2,4 GHz band, with a minimum of 60% in the 5 GHz band. The hallmark of this product is its small footprint, since it fits into many wireless devices easily.

The larger 35,9 by 15,90 mm model is for applications that require the highest level of RF performance. It gives an efficiency of at least 80% in the 2,4 GHz band with 70% minimum in the 5 GHz band. These products can be used in wireless applications including Wi-Fi access points, consumer electronics, telemedicine devices and more.

An important feature of these antennas is their dipole-style design which makes them independent from the printed circuit board dimensions used in the wireless application. Since they are ground-independent, they can be applied in any device without the constraints and concerns of PCB grounding or PCB ground-induced radiation.

The antennas are applied by simply peeling off the poly-flexible adhesive tape on the underside and sticking it on any desired surface within the device casing. Once the UFL-type coaxial connector (located at the end of the micro-coaxial cable) is connected to the device radio, the antenna is ready to use.
