Crosspolarisation characteristics of triangular microstrip antennas mo
unted on a cylindrical body are studied using a full-wave analysis. Nu
merical results of the far-zone copolarised and crosspolarised radiate
d fields at the TM10 mode for different cylinder radii and flare angle
s are calculated and analysed. A significant dependence of the crosspo
larisation level on the cylinder radius and flare angle is observed. D
etails of the results are presented.
