Abstract
The antenna array element provides an active element input impedance with a practical tuning frequency range of 3.6:1 (almost two octaves) and a wide instantaneous bandwidth. The balanced feed inputs to the element may be phased to produce any desired polarization. The antenna element is formed from two stacked crossed grid dipole elements with carefully optimized dimensions. The interelement array spacing is the maximum possible for/grating lobe free operation using a rectangular array lattice.
