can you suggest the simplest antenna design that would be useful as a passive repeater?

ang problem kasi mahina (madalas wala) ang WiFi signal sa kwarto namin. blocked by some metal structures. pag nag-relocate naman ako, dun naman sa workplace ng tatay ko mahina ang signal.

I was actually thinking of a PCB etched Yagi.

gusto ko rin sana yung BiQuad pero kulang yung materials sa bahay and wala akong time bumili.

may naka-try na bang gawan ng parabolic reflector yung rubber ducky na kasama sa wireless router? mukhang mas madali kasi kaysa gumawa ng antenna. hehehe.

A corner reflector will suffice.

mukha nga. I tried using a flat reflector and performance seem to improve. may 2 bar signal na.

I have this type of antenna. Inside its just a pcb board with a huge square track and separated by a tin plate reflector which is slightly bigger than the pcb track. It has a gain of 6db. If I have time this evening, I'll dissaemble it and measure the dimensions for you.

thanks po.

similar diyan yung design sa office para sa Wireless Phone Antenna. pero circular reflector and element, separated by a small brass cylinder.

sir yung bi-quad maganda rin.

RiDdLeR??? · « **Reply #7 on:** May 15, 2008, 06:31:36 PM »

Although the above has only 6dB gain, its much easier to construct than a bi-quad antenna. You just need a couple pf pcb boards spaced around 12.44 mm apart. The metal reflector at the back is the size of the whole pcb at the front.

thanks.

mag scavenge na lang ako ng BNC connectors sa office.

gusto ko rin sana yung BiQuad pero medyo matagal din i-construct compare sa plates lang.

BTW, I am also considering a 3d corner reflector with director. hanggang 12dbi din pala gain nun.

saan ba kayo nakatira? palakasin nyo pa ang output signal ng mga wifi repeaters nyo para naman masagap ko! hehe

rdpzycho · « **Reply #11 on:** May 15, 2008, 07:44:24 PM »

nasa Tondo pa ako. hehehe. gagawa ako back to back passive repeater para sa laptop ko, wala kasi tong external antenna port. para pwede makasagap WiFi kahit saan. hehehe.

yung wifi namin sa probinsya, gumawa lang ako ng karton tapos korteng parabol tapos sinentro ko lang yung antenna ng wireless router sa parabola. Yung karton eh yari lang sa lumang kalendaryo na binalutan ko ng aluminum foil.

Gusto ko kasi i extend yung signal para makaabot sa kabilang bahay (house ng mga tita ko). Dati very low yung signal, ngayon very good na.

ok din daw yung karton ng Pringles.

@alyas

Antenna ba yan? Sa antenna ba ng router nakakabit yan?

rdpzycho · « **Reply #15 on:** June 12, 2008, 10:29:30 PM »

ganyan din ang design ng mga antenna na ginagamit sa wireless phones ng Digitel at Bayantel. pero disc ang design.

deanc · « **Reply #16 on:** June 12, 2008, 11:22:07 PM »

Ok antenna nga yata to, mukhang may stub match sa terminal...

e-BAT · « **Reply #17 on:** June 19, 2008, 08:02:21 PM »

Help naman diyan. Nakikishare lang kasi kami ng router sa kapitbahay pano ko maiboost ung pagreceive ng signal ng wifi. Laptop lang ang gamit namin dito sa bahay. Wala rin akong masyadong idea sa antenna. If I make that parabolic antenna, where will I connect it? Line Of Sight naman.

rdpzycho · « **Reply #18 on:** June 19, 2008, 10:41:16 PM »

kung gagawa ka ng parabolic reflector, ikakabit lang dun sa mismong rubber ducky (present antenna) nung router. just make sure na nasa focus nung ginawa mong parabola yung ducky.

DEICIDE · « **Reply #19 on:** July 15, 2008, 10:08:00 PM »

pano kaya ito,

may free hotspot sa isang area na gusto mo ibato ung narereceived mong signal sa kabilang street or building??
