1. An antenna assembly comprising:
an antenna that includes a first portion and a second portion, the second portion coupled to a radio frequency (RF) port; and
a filter circuit coupled to the antenna, wherein the filter circuit includes:
a low pass filter coupled between the first portion of the antenna and a specific absorption rate (SAR) controller, the low pass filter to filter out an RF signal, and pass an SAR signal from the first and second portions of the antenna to the SAR controller, wherein the RF signal has a higher frequency than the SAR signal; and
a high pass filter coupled between the first portion of the antenna and the second portion of the antenna, the high pass filter to pass the RF signal from the first portion of the antenna to the RF port via the second portion of the antenna, and to filter out the SAR signal.
