ABSTRACT:
A capacitively-loaded loop antenna and corresponding radiation method have been provided. The antenna comprises a transformer loop having a balanced feed interface and a capacitively-loaded loop radiator. In one aspect, the capacitively-loaded loop radiator is a balanced radiator. In another, the transformed loop and capacitively-loaded loop radiator are physically connected. That is, the transformer loop and the capacitively-loaded loop radiator have a portion shared by both of the loop perimeters. Alternately, the loops are physically independent of each other. In one aspect, the perimeters have a rectangular shape. Other shapes such as round or oval are also possible. In another aspect, the planes formed by the transformer and capacitively-loaded loop radiator can be coplanar or non-planar, while both loops are orthogonal to a common magnetic near-field generated by the transformed loop. The radiator has a capacitively-loaded side, or capacitively loaded perimeter section, depending on the shape of the perimeter.
