Schemele prezentate aici se preteaza si pt banda de 5ghz cu conditia recalcularii elementeler pt lungimea de unda corespunzator fregventei de 5 ghz.
Pt alte detali trebuie sa spui ce cerinte ai pt o astfel de antena si cum vrei sa o folosesti.

Se pot obtine cistiguri foarte mari cu antene tip pachuri imprimate direct pe cablaj , dar executia lor cere precizie maxima si un anumit tip de cablaj.
In atasament ai o fotografie la o antena ce are un cistig de 28dbm cum sustine sursa.

Incearca calculatorul asta. http://www.wikarekare.org/Antenna/WaveguideCan.html .
Setezi un canal din mijlocul benzii de 5 ghz.Diametrul interior sa fie cam 38-40 mm.

Foloseste google translator,
au incercat mai multe variante in functie de diametrul radiatorului , eu am indicat sursa , tu trebuia sa te informezi.
Uite si un pdf cu tot ce trebuie pt o varianta, pe forumul rusesc sau mai facut modificari
