ABSTRACT:
A phased array of dipoles mounted above a ground plane and including capacitance plate elements made of conductive metal mounted at greater distances from ground plane than the dipoles to compensate for variations in impedance over the scan angle of the phase array. With appropriate choice of the dimensions of the capacitance plate, the spacing between the dipole elements and the ground plane, and the spacing between the capacitance plates and the ground plane, the variation of input impedance over the scan angle is greatly reduced for H-plane scan.
