Abstract
An array antenna is provided with a plurality of radiating patches, wherein each of the patches, operates in one frequency band along one direction and in a different frequency band along a second direction orthogonal to the first direction. The signals from each radiating patch are coupled to two delay lines, which traverse over a variable dielectric constant plate. A voltage potential is controllably applied to each delay line to change the dielectric constant of the VDC plate in the vicinity of that delay line, thereby introducing delay in signal travel. In order to isolate the voltage potential from the two orthogonal delay lines applied to each radiating patch, at least one of the delay lines is connected to a coupling patch, which capacitively couples the RF energy to the radiating patch.
