ANTENNA APPARATUS HAVING SENSING COMPONENT COUPLED TO FIRST ANTENNA COMPONENT TO ADDITIONALLY ACT AS SECOND ANTENNA COMPONENT AND RELATED SIGNAL PROCESSING DEVICE

摘要

An antenna apparatus includes a first antenna component and a first sensing component. The first antenna component has at least one first mode. The sensing component is a front-end component of a sensing device, wherein the sensing component is further coupled to the first antenna component to act as a second antenna component having a second mode.
