1. A phased array antenna module comprising:
a plurality of antenna units including a first antenna electrode part, a second antenna electrode part spaced apart from the first antenna electrode part, a sensing electrode part electrically connected to the second antenna electrode part, and a ground electrode part spaced apart from the first antenna electrode part with the second antenna electrode part interposed therebetween;
a capacitance sensing part connected to the sensing electrode part to output a capacitance sensing signal by detecting at least one of a capacitance change between the first antenna electrode part and the second antenna electrode part, a capacitance change between the first antenna electrode part and the ground electrode part, and a capacitance change between the second antenna electrode part and the ground electrode part; and
a module control unit electrically connected to the capacitance sensing part and the second antenna electrode part of the antenna unit, and configured to control the antenna units based on the capacitance sensing signal generated from the capacitance sensing part,
wherein the first antenna electrode part and the second antenna electrode part form a single signal path.
