ABSTRACT:
A phased antenna array is described that includes a conductive ground plane and a plurality of log-periodic antennas, each antenna having a plurality of radiating elements, each radiating element having a resonant frequency. Each log-periodic antenna extends from a common feed region at an acute angle with respect to the conductive ground plane, the angle assuring that all said radiating elements having a common resonant frequency exhibit an identical electrical distance from each other and from the ground plane.
