Abstract
A phased-array antenna panel for a super economical broadcast system is provided. The phased-array antenna panel system includes an antenna panel support member, a first pair of striplines and a second pair of striplines. The antenna panel support member includes a front reflector surface to support first and second columns of constantly-spaced, crossed-dipole radiators, a first pair of signal ground cavities disposed beneath the first column of crossed-dipole radiators, a second pair of signal ground cavities disposed beneath the second column of crossed-dipole radiators, and a rear surface including first and second pairs of signal distribution cable connectors. The first pair of striplines are respectively disposed within the first pair of signal ground cavities and are coupled to the first pair of signal distribution connectors and the first column of crossed-dipole radiators. The second pair of striplines are respectively disposed within the second pair of signal ground cavities and are coupled to the second pair of signal distribution connectors and the second column of crossed-dipole radiators.
