Fernandes, "A Three-Dimensional Directive Antenna Pattern Interpolation Method," in IEEE Antennas and Wireless Propagation Letters, vol. 15, pp. 881-884, 2016, doi: 10.1109/LAWP.2015.24789621536-12251548-5757http://hdl.handle.net/10400.8/13354An interpolation method to reconstruct the 3-D directive antenna pattern is presented. The proposed method is based on the prior knowledge of the original antenna's principal planes patterns, to which a specific weighting method is applied to obtain an approximate 3-D antenna pattern. The performance of the proposed interpolation method is evaluated against 3-D antenna patterns from three typical directional antennas, extracted from appropriate electromagnetic simulation. Finally, a comparative analysis between the proposed method and current interpolation methods present in the literature is presented.engAntenna radiation patternsDirective antennasInterpolationjournal article10.1109/lawp.2015.2478962
