Abstract

A 1×8 millimetre-wave slotted substrate integrated waveguide (SIW) array antenna is proposed and analyzed through different statistical distributions in this paper. For each statistically distributed offset position, an arithmetically progressive (AP) angular rotation has been applied to each radiating slots. A customized mathematical relationship has been modeled to make a cross-correlated non-linear mapping between each basis vector of controlling and SIW antenna parameters. A modified Expo-gaussian probability density function (PDF) has been proposed to achieve -20 dB sidelobe level reduction and 11.5° half-power bandwidth.
