Abstract
A radio frequency (RF) power monitoring device includes an RF sensor to monitor RF power transferred to a target load and an impedance of the target load and a transmission line to electrically connect the RF sensor to the target load and to transfer the RF power to the target load. A phase (φz) of the impedance of the target load is adjusted to satisfy a range of −30°+180°*n<φz<30°+180°*n (where n=−2, −1, 0, 1, or 2).
