The invention provides a micro strip antenna used for both a near-field region and a remote-field region. A micro strip antenna comprises: a first dielectric substrate; a main patch, having a triangle shape under the first dielectric substrate, configured to feed a radiation current; a second dielectric substrate over the first dielectric substrate; and a sub patch, formed under the second dielectric substrate, configured to desert a current from the main patch to provide a vertical magnetic field.

Inductively coupled antennas and methods of designing the same are disclosed. Electrically small antennas having relatively high efficiency and relatively broad bandwidth may be formed by inductively coupling an antenna loop to at least one antenna winding. Such antennas may be substantially planar. Various operating characteristics of such antennas may be adjustable by and/or dependent upon the strength of the inductive coupling between an antenna winding and an antenna loop.
