NEC-LIST: Question about SM card and SC card

Hello

I wish to model 4 reflectors for circular Array Antenna with SM
(multiple Surface Patch) cards.

Those reflectors meet to right-angle each other, and above each
reflector, put dipole, and each diplole is fed by 1V.

Theoretically, this radiation pattern result in non-direction. But it
doesn't work.

Please help me, maybe I mistake data cards.

Data cards is:

It is doubtful about the part SM and SC combinations above.

And please tell me that if wish to set some reflectors to computing, then
usually how will be set in NEC code?

SM or SP card? or it is assumed Wire-Grid ?

thank you
