inside 16dbi PCB 2.4Ghz Panel Antenna

PCB 25 * 25cm

Reflector - 283 x 283 metall plate distanced at 5 mm from CUPRUM LAYER of our PCB!!

now...just solder N-type socket in the center of the circle.... and.. its working..

11dbi 2.4Ghz PCB Panel Antenna

[kleiner-onkel]

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

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.

same antenna... other source <hr>

[kleiner-onkel]

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

Should reflector have what DIMENSION ?


answer above ...

Hi These are really great pictures you have on your post.

Do you know any good sources of info for formulas to design 2.6 ghz wimax type panel antenna.

I am having trouble finding info on the methods to calculate the panel gris size.

I have a 2.6 ghz wimax modem that I would like to increase the panel size on a PCB to mount on the roof.

The panel antenna attached to modem doesn't seem to be a good use of pcb board space.

I would like to get more sectors on the new panel. Looking for over 20dbi.

Thanks

Hi

Very nice and interesting pictures you have posted here.

Good work!

I am trying to design a bigger panel PCB for my wimax interior 2.6 ghz modem to gain stronger signal on exterior mount panel.

Do you have any links to information to calculate PCB sector sizes for 2.6 ghz.?

The panel attached to the modem now doesn't seem to be a very good use of PCB space and I would like to get an over 20 dbi gain panel in the end.

Any info or help would be great.

Thanks
D

Hi all,

I'll make this antenna but it lacks information. What is the distance between the bottom and the pcb?

Thanks for your help

[kleiner-onkel]

Hi

4-7mm, move distance and meassure with second station for best signal and best swr.
