Abstract
A bi-directional spatial power combiner grid amplifier has an array of parasitic elements between the lens and the amplifier. The elements have different impedances to radiation of a first polarization (incident radiation) and of a second polarization which is orthogonal to the first (amplified radiation), thereby providing impedance matching to both the input and the output of the grid amplifier. The elements preferably are separated slots or dipoles (some in each direction of polarization), crossed slots or dipoles, or micropatches.
