Feasability of an Ultra narrow band antenna for the internet of things

Internet of thing will soon connect billion of objects together. Interference with existing standard in the ISM bands and outside is a hot issue to solve. Ultra-narrow band modulation has recently been proposed to decrease interference for low-data rate system. To simplify frontend design, ultra-narrow band (UNB) antenna could be used to prefiltered the RF signal. A first proof-of-concept is proposed with a measured quality factor of 354 at 1.39 GHz and a total efficiency of -3.8dB.
