Multiple band capacitively-loaded loop antenna

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