Abstract

An antenna structure includes a first antenna element connected to a first port, and a second antenna element connected to a second port. The antenna structure is operable to simultaneously transceive: a first signal via electric or magnetic current flow through the first antenna element in a symmetrically excited mode in which current flows symmetrically through the first antenna element and/or an asymmetrically excited mode in which current flows asymmetrically through the first antenna element, the first antenna element resonates at a first resonant frequency; and a second signal via electric or magnetic current flow through the second antenna element in a symmetrically excited mode in which current flows symmetrically through the second antenna element and/or an asymmetrically excited mode in which current flows asymmetrically through the second antenna element, the second antenna element resonates at a second resonant frequency.
