Abstract
A multiple band capacitively-loaded magnetic dipole antenna includes a plurality of magnetic dipole radiators connected to a transformer loop where the magnetic dipole radiators include at least one capacitively-loaded magnetic dipole radiator. The transformer loop has a balanced feed interface and includes a side that provides a transformer interface of quasi loops formed by the plurality of magnetic dipole radiators. Each quasi loop has a configuration and length to maximize antenna performance within a different frequency band. The at least one capacitively-loaded magnetic dipole radiator may be formed with a meander line structure and may include an electric field bridge such as a dielectric gap, lumped element, circuit board surface-mounted, ferroelectric tunable, or a microelectromechanical system (MEMS) capacitor.
