Antenna system with active impedance matching

With the growing use of M2M [Machine to Machine] communication in the industry, it has become essential to have antennas in devices that cover a wide frequency range from 700MHz to 2700 MHz and work efficiently by being impedance matched under various environmental effects. This paper proposes a closed loop impedance matched antenna system solution to tackle this challenging issue. A novel and compact plug and play solution is proposed that can include an antenna with a dynamic tuning range of up to a few 100 MHz.
