1. A mobile device comprising:
a transceiver configured to generate a first radio frequency transmit signal of a first frequency and a second radio frequency transmit signal of a second frequency;
a front end system including a multi-throw switch having a first input configured to receive the first radio frequency transmit signal and a second input configured to receive the second radio frequency transmit signal, the front end system further including a plurality of power amplifiers including a first power amplifier including an input connected to an output of the multi-throw switch; and
an antenna array including a first antenna element including an input connected to an output of the first power amplifier, the first antenna element being a multi-resonant antenna implemented with separate resonant frequencies in different frequency bands, the first antenna element having a first resonant mode corresponding to the first frequency and a second resonant mode corresponding to the second frequency, the antenna array further including a first termination network directly connected to the input of the first antenna element and tuned to the first frequency to provide termination at the first frequency and a second termination network directly connected to the input of the first antenna element and tuned to the second frequency to provide termination at the second frequency.
