Abstract
An antenna system with switchable radiation gain includes a signal feeding element, a first antenna element, a second antenna element, a first diode, a first switch element, a second switch element, a first impedance transformer, and a second impedance transformer. The first antenna element is coupled to a first connection point. The second antenna element is coupled to a second connection point. The first diode has an anode coupled to the first connection point, and a cathode coupled to the second connection point. The first switch element and the second switch element are configured to select either the first impedance transformer or the second impedance transformer as a first target transformer, and the selected first target transformer is coupled between the first connection point and the signal feeding element.
