A hexagonal slot is etched from a finite ground plane placed on the other side of the substrate. The antenn...

A printed circular open-loop antenna is introduced as a simple structure for producing circular polarization, the antenna is fed with a coaxial probe. By introducing a gap within the circular loop a traveling-wave current is excited and thus circularly polarized radiation can be achieved. An optimized circularly polarized antenna is designed through numerical analysis using a so-called parametr...
