Georgia Institute of Technology, Atlanta, GA *Equally Credited Authors (ECAs) 1 2 With the rapid growth of mm-wave wireless technologies, phased arrays are essential to meet the stringent link-budget requirements under path losses. However, antenna array inter-element coupling distorts each antenna load from its nominal 50Ω impedance, commonly known as antenna voltage standing wave ratio (VSWR), degrading the array radiation pattern and each transmitter-element performance. Moreover, an antenna VSWR depends on the array-element location and the beamforming coefficients, complicating any correction/compensation schemes [1]. With mismatched antenna loads, the desired actual element gain, radiated power, and radiation pattern often deviate significantly from the target values. Accurate and VSWR-resilient power monitoring is a foundational technology to ensure the desired radiated power/gain per element and recover the array radiation pattern. In
