Abstract

Compact, planar inverted-F antennas are provided that radiate within multiple frequency bands for use within communications devices, such as radiotelephones. Multiple signal feeds extend from a conductive element in respective spaced-apart locations. A respective plurality of micro-electromechanical systems (MEMS) switches are electrically connected to the signal feeds and are configured to selectively connect the respective signal feeds to ground or RF circuitry. In addition, each MEMS switch can be opened to electrically isolate a respective signal feed.
