Abstract
A frequency-tunable capacitively-loaded magnetic dipole antenna includes a transformer loop having a balanced feed interface, and a capacitively-loaded magnetic dipole radiator with a tunable effective electrical length. In one embodiment, the capacitively-loaded magnetic dipole radiator includes a tunable electric field bridge. For example, the capacitively-loaded magnetic dipole radiator may comprise a quasi loop with a tunable electric field bridge interposed between the quasi loop first and second ends. The electric field bridge may be an element such as a ferroelectric (FE) tunable capacitor or a microelectromechanical system (MEMS) capacitor, to name a couple of examples. In certain embodiments, the capacitively-loaded magnetic dipole radiator includes a quasi loop with a loop perimeter. The effective electrical length of the radiator is changed by adjusting the perimeter using an element such as a MEMS switch, or a semiconductor switch.
