Abstract
An antenna includes an electrical excitation component and a core component. The electrical excitation component has and input and a conducting component. The conducting component can conduct current from the input. The core component has a magnetic film, having a substrate and a magnetic material layer, wound around a rectangular mounting plate. The core component can have a magnetic current loop induced therein. The electrical excitation component is arranged such that concentric magnetic fields associated with current conducted through the electrical excitation component are additionally associated with a magnetic current loop within the core component.
