ISM standalone antenna

25 November 2015 Telecoms, Datacoms, Wireless, IoT

Molex’s 868 and 915 MHz ISM standalone antenna with leading-edge MobliquA technology combines high performance without ground-plane restrictions for significant cost savings and easy integration into wireless devices. Designed for compact industrial and other wireless applications operating the license-free 868 and 915 MHz frequencies, they give smart meter, medical device and automotive makers value for their investments.

Featuring Molex’s patented MobliquA bandwidth enhancing technology, the antenna’s indirect radiator-feed design enables dual-band ISM operation with reduced antenna volume of 75% compared with conventional dipole type antennas. According to Molex, the small 79,0 by 10,0 mm footprint of the antenna offers greater space savings than any equivalent standalone antenna in the industry over the same frequency bands.

An important feature of this antenna is its balanced feed structure. It facilitates true ground-plane-independence which enables easy integration of the antenna without the concerns of PCB size limitations and land ground-induced currents. It also frees up additional costs associated with electronic circuitry and engineering resources normally required for antenna frequency tuning and optimisation over these bands.

Molex’s ISM antenna design provides reflection coefficient values of -11 dB to -16 dB in both bands. Combined with radiation efficiencies of between 50% and 67%, this high-performance standalone antenna is ideal for applications that need superb performance and mechanical robustness.

The 105262 series of standalone antennas are very easy to use, by simply peeling off the poly-flexible adhesive tape on the underside and sticking it on any desired location within the device casing. Next, mount the UFL-type coaxial connector at the end of the micro-coaxial cable is mounted to the device radio and the antenna is ready to use. For added convenience and design flexibility, the cables come in lengths of 100, 150 and 200 mm.
