Abstract

This invention pertains to a handheld wireless communicater's antenna or, more specifically a beam-flipping electromagnetic dipole antenna that is composed of a pair of spacetime-conjugated near-resonance electric and magnetic dipoles. The magnetic dipole is a large conducting loop of about 1.5 wavelength with high radiation intensity and efficiency, consisting of 4 or more electromagnetically coupled arms that are connected to a pair of driveplates for producing reversible loop currents. When held to a user's ear, the new antenna can automatically direct its radiation beam outward from the user, thus reduce microwave radiation to the user's head to a minimum. Meantime, the new antenna can also expand its effective radius, and extend its battery's useful duration. It has the highest antenna gain and widest signal bandwidth among all antennas sizing 0.01 cubic wavelength or less.
