Dim: 80 x 80 x 61 (mm)
Gain: 8 dBi
FB ratio: > 40 dB
Beamwidth > 45o
S11: -20 dB to -25 dB at 2.35GHz
The case is made of aluminum 2mm thick.

When removing the case, and adding a metal back you get:
Dim: 70 x 74 x 2 (mm)
Gain: 10 dB
FB ratio: > 40 dB
By moving metal back 3mm away, you get 1.5 dB more.
The metal back is made of aluminum 2mm thick.

An array of 4 elements has been simulated providing:
Dim: 200 x 100 x 5 (mm)
Gain: 15 dB
FB ratio: > 40 dB
Beamwidth > 50o
More accurate results will follow.

All constructions were made using FR4 board 1mm thick, and the connector was of N-type.
Design, simulation and testing (at qualified EMI labs) made by Nick (ee9nt) and Vivi
