The cross‐polarization characteristics of a rectangular microstrip patch antenna mounted on a cylindrical surface are investigated by using the modal‐expansion theory. The case of the patch antenna excited at TM 01 mode is treated. Numerical results showing the variations of the cross‐polarization level for various aspect ratios and different curvature radii are given. A great dependence of the cross‐polarization level on the curvature radius of the cylindrical microstrip patch antenna is observed. The effects of feed positions on the cross‐polarization characteristics are also analyzed.
