The more dielectrics the more LOSSes...

 

What about dieletric as a microwave lens? It's probably the only chance to get more than 17dBi.

PES (Styrofoam) low density...1.075-1.1 Dielectric Constant (almost NO LOSSES)

add a rim and ring...

[eco32 38]

I can only use dipole with reflector with out  circle and without ring in Matlab, i got 15,4dBi on this moment and optymalisation is in progress, 
Radius 47cm
Heightt 21cm
Spacing ~50cm

freq 1296MHz

@eco32 you NEED to try CST...is very intuitive and fast...and better results...

backfiring CIRCULAR PATCH should have better shape...LOBE

I've had CST installed for over a year, just haven't had time to switch. How to get started? Colleagues, if you can help me get started, it will be full  of benefit for everyone's in the community.

bacfire VS dish

1296MHz similar diameters,  after long optimalisation  in Matlab (end usage of thos tool soooooon)

I wonder why you make a radiator with a diameter of 537 mm, when you better use a parable from the trade....???!!!

,,, a lot of work for nothing....!!!
