A microstrip antenna system is comprised of either a single antenna element (patch) or a plurality of stacked antenna elements having one or more feedpins connected to a corresponding number of conductive elements (flags) capacitively coupled to the antenna element or elements. The one or more feedpins have an inductive reactance which is cancelled by trimmed flags to provide the capacitance necessary to cancel the inductance for tuning the one or more antennas and providing maximum gain and minimum VSWR.
