  1. Been beating around the bush for years to find a Good 4x4 patch array... Higher than 21 dbi , good impedance through the whole band,low enough vswr, under -20dbi side lobes... the original design is for 12,5 ghz and almost none side-lobes Power distribution Ratio 1:5:5:1 Changed it to WiFi , distribution ratio 1:1:1:1 (Original design Eliminated Sidelobes at the COST of 1,5-2dbi of gain) I'm happy (some testing still needed ) REAL dielectric constant of Polystyrene foam is a guess (1.02-1.05)
  2. Interesting design , don't know about performance... Polyurethane aluminum PATCHES Manufacturer
  3. Originally designed for 5.8 (with HIGH LOSSES and low gain) Inverse engineered to 2,4 ghz wjith High GAIN and Better Efficiency s on FR4 ...modelling right now...almost there...Close to 20dbi
  4. What you think JOMY...? 19-20dbi on 12 PATCHES...is it doable...? array franklin high gain.pdf array franklin high gain2.pdf
