it looks like patch with parasitic element, and looks like easy tu manufacture because there are just only 3 round elements.

 Any dimensions for that proposal ? :)

Generally dont looking for broadbang. At this moment looking for two antennas with higher gain:
One for 700MHZ and second for 750mhz. Easy to manufacture on CNC from FR4 laminate.

Could be made to ANY frequency , Circular pol (could be made lineal easy) efficiency could be better NOT using FR...

Thanks, but looks like has quite big footprint. 
this one i've provided is quite small - 200mm diameter. Generally i could sacriface those 10 dbi over smaller footprint.
Clanon. So such design but linear and for 750 ?

Can someone also simulate Yagi on FR4 for 750 ?

Easier ,for me, if  YOU choose ANY 2-3 patches design (10dbi)  ( need a frontal picture)

and then we'll make it work at 725mhz...
