Patent ID: 8059049

Claim:
A dual band antenna array, comprising: a folded circuit board comprising a dielectric layer and a conductor layer pattern formed on a first surface of the dielectric layer, the circuit board folded in a plurality of folds to form a pleated structure defining a first array of radiator structures on said first surface, the first array of radiator structures configured for operation in a first frequency band in a first polarization sense; a second array of radiator structures configured for operation in a second frequency band in a second polarization sense, the second array of radiator structures being on a side of the dielectric layer opposite the first surface, wherein the second frequency band is different from the first frequency band; a conductor trace pattern formed on the folded circuit board to carry control signals, DC power and RF signals; and a plurality of active RF circuit devices attached to the folded circuit board in signal communication with said conductor trace pattern.
