EiFi 4321901 Feuerbällchen Anzünder,...
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

[quote:kleiner-onkel]same antenna... other source

another Panel from D-Link ANT24-1800 with 18dbi

Hello, I have the question in which points you should solder on the cable H155, and what there should be the dimensions of the
reflector?

Thanks for your anserw.

The red dot is the inner lead... reflector the ouder


******************************************************

The diameter between reflektor and pcb is 6mm... the size of the reflektor ist the same like the pcb (shown in the pdf file) ... read out for best signal... if you lucky enough ask a university for network analyzer to measure best swr
