METHOD OF ELIMINATING RESONANCES IN MULTIBAND RADIATING ARRAYS
摘要:
A multiband radiating array according to the present invention includes a vertical column of lower band dipole elements and a vertical column of higher band dipole elements. The lower band dipole elements operate at a lower operational frequency band, and the lower band dipole elements have dipole arms that combine to be about one half of a wavelength of the lower operational frequency band midpoint frequency. The higher band dipole elements operate at a higher frequency band, and the higher band dipole elements have dipole arms that combine to be about three quarters of a wavelength of the higher operational frequency band midpoint frequency. The higher band radiating elements are supported above a reflector by higher band feed boards. A combination of the higher band feed boards and higher band dipole arms do not resonate in the lower operational frequency band.
