1. A mobile device comprising:
a front end system including a first signal conditioning circuit configured to condition a first radio frequency signal of a first frequency, and a second signal conditioning circuit configured to condition a second radio frequency signal of a second frequency that is lower than the first frequency; and
an antenna structure configured to diplex the first radio frequency signal and the second radio frequency signal, the antenna structure including a rectangular-shaped antenna configured to handle the first radio frequency signal and an L-shaped antenna electromagnetically coupled to the rectangular-shaped antenna and configured to handle the second radio frequency signal, the L-shaped antenna including a first portion along a first side of the rectangular-shaped antenna and a second portion along a second side of the rectangular-shaped antenna, the antenna structure further including a first radial stub extending from a third side of the rectangular-shaped antenna opposite the first side.
