EnglishThis letter presents a width-modulated microstrip line leaky-wave antenna (LWA) with substrate-integrated waveguide and microstrip feeding. In particular, the planar antenna system consists of an integrated surface-wave launcher and three identical rows of quasi-periodic width-modulated microstrip lines for TM leaky-wave excitation, which produces a tailored binomial-like aperture distribution on the guiding surface. The behavior of the antenna when changing the width-modulated lines for different aperture distributions is also analyzed and presented. The measured LWA demonstrates a fan beam pattern in the far field with realized gain values greater than 10 dBi and with a beam direction of about −20◦ from broadside at 23 GHz. Also, far-field measurements and near-field data indicate that the half-power beamwidth is below10◦, and the position of the main beam maximum is relatively stable, i.e., ranging from about −23◦ to −15◦ between 23 and 24 GHz. The measured prototype is also well matched over these frequencies and |S11| < −20 dB at 23.5 GHz.
