Abstract
An antenna system is provided which employs RF and DC coupling across a dielectric. RF coupling is achieved using low cost and low loss RF coupler pairs such as quarterwave patches that are mounted opposite each other on either side of a dielectric. The feeds of the patches are aligned so as to be directly opposite each other, and the patches are mounted against the dielectric. A voltage booster circuit can be provided to increase input supply voltage for DC coupling that is adjustable to accommodate the thickness of the dielectric.
