More Information
Summary:A communication device with an RF (Radio Frequency) node and a detection node includes a first radiation element, a second radiation element, a first inductor, a second inductor, a third inductor, a first capacitor, and a second capacitor. The first radiation element is coupled to a first node. The second radiation element is coupled to a second node. The first inductor is coupled between the RF node and the ground voltage. The first capacitor is coupled between the RF node and the first node. The second inductor is coupled between the first node and the second node. The second capacitor is coupled between the second node and the ground voltage. The third inductor is coupled between the detection node and the second node. An antenna structure and a sensing pad are formed by the first radiation element and the second radiation element.
