Abstract
The paper presents the effects on the performance of a leaky-wave antenna when curved cylindrically. A slot array antenna based leaky-wave architecture based on a corrugated substrate integrated waveguide (CSIW) guiding structure has been used for the study. The antenna is simulated on a thin substrate of height h = 0.254 mm for conformality and is shown to operate at 24 – 27 GHz for applications in millimeter-wave 5G and beyond. The change in antenna gain, beam angle and half-power beamwidth with the change in fold curvature has been highlighted.
