1. An antenna structure comprising:
a first antenna element connected to a first port; and
a second antenna element connected to a second port;
wherein one of the first antenna element and the second antenna element is a slot antenna element, the other one of the first antenna element and the second antenna element is a slot antenna element or a wire antenna element;
the antenna structure is operable to simultaneously transceive:
a first signal via electric or magnetic current flow through the first antenna element to or from the first port, wherein the first antenna element operates 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, thereby causing the first antenna element to resonate at a first resonant frequency, and
a second signal via electric or magnetic current flow through the second antenna element to or from the second port, wherein the second antenna element operates 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, thereby causing the second antenna element to resonate at a second resonant frequency, wherein the first resonant frequency is the same as the second resonant frequency.
