Abstract
A phased array antenna includes a plurality of phased array antenna modules and associated antenna elements. Further, at least one of the phased array antenna modules may also include a temperature sensor for measuring a temperature of the at least one phased array antenna module. More particularly, the temperature sensor may include a capacitor and a circuit element coupled in series with the capacitor having a resistance that varies with temperature. Additionally, the at least one phased array antenna module may further include a module controller for charging/discharging the capacitor through the circuit element, measuring a charging/discharging time required to charge/discharge the capacitor to a predetermined threshold, and determining the temperature of the at least one phased array antenna module based upon the charging/discharging time.
