Abstract :
An approximate formula has been recently proposed for the on-axis gain of rectangular waveguide antennas, that include open-ended rectangular waveguides and sectoral and pyramidal horns (see Selvan, K.T., IEEE Trans. Antennas Propagat., vol.47, p.1001-4, 1999). This formula is an approximate generalization of S.A. Schelkunoff\´s horn-gain formulas (see "Electromagnetic Waves", Van Nostrand, p.360-4, 1943). Gain measurements are reported for the gains of E plane and H plane sectoral horns and are used in an examination of the accuracy of Selvan\´s formulas. To the best of the authors\´ knowledge, these are the first ever measurement efforts on the gain of H-plane sectoral horns
