Leaky wave enhanced phased array for the reduction of the grating lobe level

It is possible to reduce the cost of building phase arrays by reducing the number of active transceivers at the cost of having grating lobes and a reduced gain For small coverage angle applications for applications with a limited coverage angle. Here we want to show that dielectric and FSS super-layers can be used to improve the performances of such phased arrays by achieving an angular filtering at the array element pattern level. Such angular filtering can be synthesized with leaky waves.
