An electronically steerable parasitic array radiator (ESPAR) antenna system that includes an ESPAR antenna, a GPS receiver, a GPS low-noise amplifier, a power detector module, and a central processing unit. The GPS receiver is connected to the ESPAR antenna as a separate component. The GPS low-noise amplifier strengthens a signal to propagate through the transmission line and operates in the L1 and L2 GPS bands. The power detector module provides additional amplification for noise quantification. The power detector receives an RF power level and converts the RF power level into a DC voltage output. The central processing unit includes memory that is capable of storing the DC voltage output from the power detector.

An antenna array for a high frequency device includes a plurality of antenna elements used for a radar device and arranged in a two-dimensional array in a predetermined area.
