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. 2.4/5 GHz Standalone Antennas, RoHS-compliant, Halogen-free 47950 2.4/5 GHz Standalone Antennas, 34.90 by 9.00mm (1.37 by 0.34") and 35.90 by 15.90mm (1.41 by 0.61") variants 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 groundindependent 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.
