ABSTRACT:
A meander line capacitively-loaded magnetic dipole antenna is disclosed. The antenna includes a transformer loop having a balanced feed interface, and a meander line capacitively-loaded magnetic dipole radiator. The meander line capacitively-loaded magnetic dipole radiator also includes an electric field bridge. For example, the meander line capacitively-loaded magnetic dipole radiator may include a quasi loop with a first end and a second end, with the electric field bridge interposed between the quasi loop first and second ends. The electric field bridge may be an element such as a dielectric gap, lumped element, circuit board surface-mounted, ferroelectric tunable, or a microelectromechanical system (MEMS) capacitor. The transformer loop has a radiator interface coupled to a quasi loop transformer interface. In one aspect, the coupled interfaces are a shared perimeter portion shared by both loops.
