Phased-Array Antenna Panel for a Super Economical Broadcast System

A phased-array antenna panel, including:

• a front reflector surface including a pair of raised sections to respectively support first and second staggered columns of constantly-spaced, crossed-dipole radiators;
• a first pair of signal ground cavities, extending longitudinally along the support member, disposed beneath the first column of crossed-dipole radiators;
• a second pair of signal ground cavities, extending longitudinally along the support member, disposed beneath the second column of crossed-dipole radiators;
• and
• a rear surface, including a first pair of signal distribution cable connectors disposed beneath the first pair of signal ground cavities, and a second pair of signal distribution cable connectors disposed beneath the second pair of signal ground cavities.

A phased-array antenna panel system, comprising:

• a first column of constantly-spaced, transverse quadrilateral crossed-dipole radiators, each having a pair of inner dipole conductors;
• a second column of constantly-spaced, transverse quadrilateral crossed-dipole radiators, each having a pair of inner dipole conductors, arranged in a staggered relationship with respect to the first column of crossed-dipole radiators;
• an antenna panel support member, including:
• a front reflector surface to support the first and second columns of crossed-dipole radiators,
• a first signal ground cavity, extending longitudinally along the antenna panel support member, disposed beneath at least a portion of the first column of crossed-dipole radiators,
• a second signal ground cavity, extending longitudinally along the antenna panel support member, disposed beneath at least a portion of the first column of crossed-dipole radiators,
• a third signal ground cavity, extending longitudinally along the antenna panel support member, disposed beneath at least a portion of the second column of crossed-dipole radiators,
• a fourth signal ground cavity, extending longitudinally along the antenna panel support member, disposed beneath at least a portion of the second column of crossed-dipole radiators, and
• a rear surface, including a first signal distribution cable connector disposed beneath the first signal ground cavity, a second signal distribution cable connector disposed beneath the second signal ground cavity, a third signal distribution cable connector disposed beneath the third signal ground cavity, and a fourth signal distribution cable connector disposed beneath the fourth signal ground cavity;
• a first stripline, disposed within the first signal ground cavity and coupled to the first signal distribution connector and the first inner dipole conductors of the first column of crossed-dipole radiators;
• a second stripline, disposed within the second signal ground cavity and coupled to the second signal distribution connector and the second inner dipole conductors of the first column of crossed-dipole radiators;
• a third stripline, disposed within the third signal ground cavity and coupled to the third signal distribution connector and the first inner dipole conductors of the second column of crossed-dipole radiators;
• and
• a fourth stripline, disposed within the fourth signal ground cavity and coupled to the fourth signal distribution connector and the second inner dipole conductors of the second column of crossed-dipole radiators.
