Abstract
Technologies directed to calibrating phased array antennas are described. A processing device of a communication device causes a first radio to send a first signal via a first antenna element. The first signal has a set of tones. Each tone of the set of tones has a frequency within a fixed frequency range. The processing device causes a second radio to receive a second signal via a second antenna element. The second signal is a response to the first signal. The processing device determines that there is a difference between the second signal and a reference signal. The processing device adjusts at least one of a phase parameter value, a gain parameter value, or a time-delay parameter value of a radio frequency component based on the difference.
