Abstract
A mobile device includes an antenna structure, a signal source, and an IPMC (Ionic Polymer Metal Composite). The signal source is configured to excite the antenna structure. The IPMC is configured as a flexible actuator to adjust a resonant length of the antenna structure in such a manner that the antenna structure is capable of operating in multiple bands.
Claims19
A mobile device, comprising:
- an antenna structure;
- a signal source, configured to excite the antenna structure;
- and
- an IPMC (Ionic Polymer Metal Composite), wherein the IPMC is configured as a flexible actuator to adjust a resonant length of the antenna structure in such a manner that the antenna structure is capable of operating in multiple bands,
- wherein the antenna structure comprises a first metal element, a second metal element, and a connection metal element, wherein the first metal element is coupled to the signal source, and a bending state of the IPMC is changed according to a voltage difference such that the IPMC causes the connection metal element to selectively couple or uncouple the first metal element to the second metal element.
