1. A mobile device comprising:
a front end system including a first radio frequency signal conditioning circuit configured to condition a first radio frequency signal of a first frequency, and a plurality of second radio frequency signal conditioning circuits configured to condition a plurality of second radio frequency signals of a second frequency that is greater than the first frequency; and
an antenna structure including a plurality of switches operable in a first mode and a second mode, and an antenna array of including a plurality of antenna elements interconnect by the plurality of switches, the antenna array operable to handle the first radio frequency signal in the first mode, and to handle the plurality of second radio frequency signals in the second mode, the plurality of switches configured to join the plurality of antenna elements in the first mode to collectively operate the plurality of antenna elements as a planar inverted F antenna, and the plurality of switches configured to open in the second mode to operate the plurality of antenna elements as an array of antenna elements that provides beamforming.
