FEATURES AND BENEFITS
SPECIFICATIONS
Molex’s class-leading 2.4/5GHz standalone antennas combine
ground-plane-independent design with high-radiation efficiency to give
customers better connectivity and reduced development time for wireless devices
Key to any wireless applications that impact the most critical design variables
such as power efficiency, antenna coverage and radio-link quality is the
antenna’s Total Radiation Efficiency. Molex’s 2.4 and 5GHz dual-band,
standalone antennas offer customers maximum radiation efficiencies over a wide
range of wireless applications, with the convenience of easy-to-use and
easy integration features.
Molex’s series 47950 antennas include the small footprint 34.5 by 9.00mm
version that delivers 75% minimum total efficiency in the 2.4GHz band, with
a minimum of 60% in the 5GHz band. The hallmark of this product is its
small footprint, since it fits into many wireless devices easily. The larger 35.9
by 15.90mm version antenna is for applications that require the highest level
of RF performance. It gives an efficiency of at least 80% in the 2.4GHz band
with a 70% minimum in the 5GHz band. These products can be used in wireless
applications including †Wi-Fi access points, consumer electronics, telemedicine
devices and more.
Another important feature of Molex’s 2.4/5GHz standalone antenna is its
dipole-style design which makes it independent from the PCB dimensions used
in the wireless application. Molex’s 2.4/5GHz standalone antennas are ground-
independent and can be applied in any device without the constraints and
concerns of PCB grounding or PCB ground-induced radiation.
Molex’s 2.4 and 5GHz standalone antennas are very easy to use. Simply peel
off the liner from the polyflexible adhesive tape of the antenna and stick it in the
desired location within the device casing. With its mini coaxial cable and
terminal MHF connector, the antenna then connects to the device radio via an
MHF SMT receptacle.
