In this paper, we present a small, wide-band, Inverted-L Antenna (ILA) with non-Foster matching. The antenna's size is 9.5×19.5mm2 and it is integrated on a Printed Circuit Board (PCB) of 90×35mm2. A design procedure is presented and sensitivity and stability analysis are performed. Experiments show that the non-Foster matched antenna has (S11 < -10dB) impedance bandwidth of 92.2% at a central frequency of 1.5GHz, whereas the passive antenna (without the non-Foster matching) has an impedance bandwidth of 12.6% at 2.46GHz.
