Abstract
A magnetic current dipole feeding structure for patch and dielectric resonator antennas is disclosed in which a wire coil helix is placed above the ground plane and below the patch or top of the dielectric resonator block, the coil having half wound in a right-hand orientation and another half in a left-hand orientation, meeting at a common point in the middle. One end of the double torsion coil can be excited with radio frequency (RF) signals, and the other can be grounded on the ground plane. Some embodiments have the other end fed by an equal signal. These double torsion coils can be used in pairs to provide differential feeding to the patch or dielectric resonator, and pairs placed orthogonally to a first pair can be used for another polarization.
