Dual-Band 2,4Ghz / 5Ghz Omni WIFI Antenna
Here is the scans of inside - very thin pcb board is used.
Some time ago I needed some 5ghz antennas - this is the first thing that I bought.
Dual-band 11a/g 7/5dBi Indoor Omni Antenna from trendnet.
The papers says :
| Frequency Range | 802.11a: 4.9 ~ 5.875GHz 802.11b/g: 2.4 ~ 2.5GHz |
| Gain | 802.11a:7dBi 802.11b/g:5dBi |
| VSWR | 2.0:1 |
| Polarization | Linear, vertical |
| HPBW/ Horizontal | 360° |
| HPBW/ Vertical | 802.11a:25° 802.11b/g: 35° |
The stupid thing is that on the site specification and in pdf data sheets was said that this antenna have VERTICAL polarization, but now I can see that omnidirectional pattern came whit horizontal polarization!

This may be the reason why I am not happy whit this wifi antenna and it is still laying on my desk.
I will test it again when I have some time.
The other small wifi antenna that I have from trendnet is working great - I have small 5ghz link whit it - these days maybe will scan ti too.

hallo, i want to build(make) this dual band of the antenna that you show it.
but i have trouble went I want to make it because the size of the accurate of the PCB layout. now iwant some help can you give me the size of the bord layout with specific. sorry if my English not good well. give me reply on my mail. Thanks
regards.

Sorry if my respons is too long. i’m verry bussy. i need the dimension of the “Dual-band 11a/g 7/5dBi Indoor Omni Antenna from trendnet” that you have bought but you not happy, or you have another picture or layout PCB about Dual-band Omni Antenna wich can 2,4 Ghz & 5 Ghz frequency?.sorry if i can answer your question right now. Thanks alot for your help.
