Abstract
A vertically polarized dipole or bicone antenna is positioned cylindrically with in many cylindrical layers of polarizing grids that slowly rotate the incident field to cross 0 degrees, i.e., 90 degrees to the horizon, and to attenuate or minimize the effects of gain nulls from reflections off of the innermost grid layer. Such an antenna is used for detecting both horizontal and vertical polarized signals over a broad bandwidth whereby the response to both polarizations is equal.
