element Capacitive Coupled To a Square Ring with Surface
Mounted Conical Horn. The designs adopt contemporary
techniques; probe feeding, square patch, surrounded ring
and surface mounted conical; horn. The composite effect of
integrating these techniques and introducing conical horn, offer
a low profile, high gain and compact antenna element. The slant
length of the horn is only λo/8 to achieve high gain ie 11.16dBi.
the structure has been simulated on a 3-D EM simulator, CSTStudio-08 to achieve high gain and hence directivity
