ABSTRACT:
A method according to an aspect of the present invention includes determining a phase offset by simultaneously providing a calibration signal to a first element of an antenna and a second element of the antenna opposite the first element. The method further includes receiving an intermix signal by a third element of the antenna, measuring an amplitude characteristic for the intermix signal, and determining a phase offset based on the amplitude characteristic. The phase offset can be used to adjust a signal provided to the first element so that signals transmitted from the first element and second element are in phase with each other. This method can account for phase errors due to the construction or design of the antenna, and allows antenna elements to be calibrated without the need for phase detector devices.
