Abstract :
An improvement of a quasi-optical frequency doubler based on crossed dipoles is proposed. The directivity of the dipole antenna is increased by adding parasitic elements similar to the Yagi-Uda approach. Layout and promising measured results of a structure with one reflector are presented and further steps for possible improvements suggested.
