* Highly efficient (88...125% aperture efficiency per frontal footprint 15x15")
* excellent matching (SWR<1.6)
* unbalanced output - direct coax or LNA feed, no balun
* high Front/Rear (18+ dB)
* smooth/wide radiation pattern (no sidelobes, all radiation in one smooth sector)
* high tolerance to build inaccuracy (no critical dimensions)
I will simplify design later, this one is taken from MIMO antenna with dual-probe feed.
