FREQUENCY SELECTIVE MULTI-BAND ANTENNA FOR WIRELESS COMMUNICATION DEVICES |
摘要 |
A multi-band antenna with improved antenna efficiency across a broad range of operative frequency bands with reduced physical size is described. The multi-band antenna includes a modified monopole element coupled to multiple antenna loading elements variably selectable to tune to one of a plurality of resonant frequencies. In one exemplary embodiment, the modified monopole element has a geometry other than that of a traditional monopole element and includes a switch array disposed between the modified monopole element and the multiple antenna loading elements and configured to couple a selected one or more of the antenna loading elements to the modified monopole element when tuning to a desired one of the plurality of resonant frequencies. The multi-band antenna resonant frequency is controlled by a wireless communication device selecting among the multiple antenna loading elements for tuning the multi-band antenna between operative frequency bands. |
