  • Abstract
    A geometrical theory of the resonant frequencies and radiation Q -factors of 45\\deg -45\\deg -90\\deg , 60\\deg -60\\deg -60\\deg , and 30\\deg -60\\deg -90\\deg triangular microstrip patch antennas is developed, based upon the rereflection of rays making up the field underneath the patch. Extremely simple formulas for Q_{r} are obtained, which enables an extensive comparison of relative radiation Q for various patch shapes to be made. This theory replaces other much more cumbersome expressions from the literature, or gives new formulas for some cases for the first time.
