  2. if you are going to dramatically change feed port design - you need to optimize port capacitance. -j 20 ... -j 60 is too much capacitance (remove or decrease improvised capacitor) Request for this antenna was direct TV cable mount (via F-screw soldered to reflector) P.S. do 75 Ohm SMA exist?
  3. jX curve is heaviliy dependent on port design - diameter and length of feed pin wire + size of lip-capacitor at port Jomy has SWR=1.41 @ 2.13 GHz, my model has SWR50=1.44 @ 2.13 GHz
  4. the same design principles apply to hexagonal patches. I find ellipses convenient, so I calculated dimensions only for ellipse. Pseudo-ellipses work pretty much the same, one need to calculate exact dimensions
  5. I simplified this design - more compact reflector (14x22 cm flat reflector is viable minimum) and single copper wire. For 2x2 ellipse design - same approach. only copper wire and no additional L/4 stripline transformer
