Abstract
An integrated circuit transmission system includes a dielectric substrate wave guide and first and second substrate antennas. A substrate transmitter is operable to produce an radio frequency (RF) signal, the RF signal having first and second components. A micro-strip resonator filter module generates a filtered RF signal by adjusting phases of the first and second components of the RF signal via selection of one of a plurality of selectable tap points. A third substrate antenna generates a beam formed signal for transmission through the dielectric substrate wave guide, wherein the beam form signal is directed, via the filtered RF signal, to either the first substrate antenna or the second substrate antenna.
