Abstract
There is disclosed a planar antenna for very low frequencies. The antenna has a high impedance and can be matched to 50 ohm or higher impedance stages. The antenna may be used for applications which require a short range such as a wireless peripheral. The antenna operates only in its near-field and does not require a complex lossy impedance matching network, since the input impedance is large.
