Aspects of the present disclosure includes a phase shifter that includes a first meandering transmission line having a first input configured to receive a first input signal and a first output configured to provide a first output signal; and a plurality of switches configured to adjust an effective electrical length of the first meandering transmission line. In some embodiments, a method for processing a millimeter wave communication signal in a phase-array antenna includes determining a phase shift appropriate for the millimeter wave communication signal; determining configuration of a plurality of switches configured to adjust an effective electrical length of a first meandering transmission line configured to receive the millimeter wave communication signal; and setting the plurality of switches.
