Spiral faz dizili anten: kavram ve teknoloji<\/h2>\n

Trinity Radionics, 5 MHz ile 8 MHz aral\u0131\u011f\u0131nda<\/strong> kapsaml\u0131 ara\u015ft\u0131rma ve deneylerden sonra radyonik tarz\u0131 sinyal \u00e7al\u0131\u015fmalar\u0131nda s\u00fcrt\u00fcnme y\u00fczeyi (stick pad), verici veya harici anten olarak kullan\u0131lmak \u00fczere \u00e7ok fazl\u0131 bir Ar\u015fimet spirali anteni geli\u015ftirdi.<\/p>\n

Anten kavram\u0131 daha geni\u015f bir frekans aral\u0131\u011f\u0131nda incelenebilse de tasar\u0131m, 5 MHz ile 8 MHz<\/strong> \u00e7al\u0131\u015fma aral\u0131\u011f\u0131 temel al\u0131narak hesapland\u0131 ve optimize edildi. Bu aral\u0131k, belirli Trinity Radionics tasar\u0131mlar\u0131nda enerji dengelemesi, niyet yay\u0131n\u0131 ve s\u00fcptil enerji uygulamalar\u0131 i\u00e7in kullan\u0131l\u0131r.<\/p>\n

Ar\u015fimet ve \u00fcstel spirallerin ara\u015ft\u0131r\u0131lmas\u0131<\/h2>\n

Geli\u015ftirme s\u0131ras\u0131nda hem Ar\u015fimet hem de \u00fcstel spiral \u00f6r\u00fcnt\u00fcleri incelendi. Her spiral t\u00fcr\u00fcn\u00fcn matematiksel \u00f6zellikleri ve pratik avantajlar\u0131 farkl\u0131d\u0131r; her biri tasar\u0131mda farkl\u0131 dengeler g\u00f6zetmeyi gerektirir.<\/p>\n

Ar\u015fimet spiralinin kollar\u0131 uzun olabilir; bu da d\u00fc\u015f\u00fck frekanslarda devre kay\u0131plar\u0131n\u0131 art\u0131rabilir. Sar\u0131m a\u00e7\u0131s\u0131 da merkezden d\u0131\u015f \u00e7apa do\u011fru de\u011fi\u015fir. \u0130\u00e7 b\u00f6lge y\u00fcksek frekanslarda \u00fcst mertebeden modlar\u0131 uyarabilirken d\u0131\u015f b\u00f6lge d\u00fc\u015f\u00fck frekanslarda daha iyi bir \u0131\u015f\u0131ma \u00f6r\u00fcnt\u00fcs\u00fcn\u00fc destekleyebilir.<\/p>\n

\u00dcstel spiraller daha geni\u015f bir frekans aral\u0131\u011f\u0131nda daha tekd\u00fcze davran\u0131\u015f sunabilir. Ancak Trinity Radionics\u2019in 5 MHz ile 8 MHz<\/strong> civar\u0131nda k\u0131sa dalga odakl\u0131 \u00e7al\u0131\u015fma hedefi i\u00e7in tercih edilen yap\u0131 Ar\u015fimet spirali oldu.<\/p>\n

D\u00f6rt katmanl\u0131 spiral PCB yap\u0131s\u0131<\/h2>\n

Anten tasar\u0131m\u0131, d\u00f6rt katmanl\u0131 bir PCB yap\u0131s\u0131<\/strong> kullan\u0131r; bu katmanlara \u00f6zenle hesaplanm\u0131\u015f d\u00f6rt spiral yap\u0131 yerle\u015ftirilmi\u015ftir.<\/p>\n

Spiral iz geni\u015fli\u011fi, iz aral\u0131\u011f\u0131, spiral say\u0131s\u0131, katmanlar\u0131n yerle\u015fimi ve PCB katman diziliminin davran\u0131\u015f\u0131 geli\u015ftirme s\u00fcrecinde hesapland\u0131. Katmanlar aras\u0131ndaki ince dielektrik ayr\u0131m, anten i\u00e7indeki faz etkile\u015fimini desteklemek \u00fczere tasarlanm\u0131\u015f kompakt bir kapasitif yap\u0131 olu\u015fturur.<\/p>\n

Bu katmanl\u0131 yap\u0131, antenin radyonik tarz\u0131 yay\u0131n, s\u00fcrt\u00fcnme y\u00fczeyi kullan\u0131m\u0131 ve s\u00fcptil enerji deneyleri i\u00e7in kompakt bir \u00e7ok fazl\u0131 yap\u0131 olarak \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flar.<\/p>\n

Besleme k\u00f6pr\u00fcs\u00fc ve kapasitif kuplaj<\/h2>\n

Anten tasar\u0131m\u0131n\u0131n en \u00f6nemli par\u00e7alar\u0131ndan biri spiral besleme k\u00f6pr\u00fcs\u00fcd\u00fcr<\/strong>. Besleme k\u00f6pr\u00fcs\u00fc spiralin merkezinde yer al\u0131r; ama\u00e7lanan frekans aral\u0131\u011f\u0131na ve yay\u0131n bi\u00e7imine g\u00f6re rezistif veya kapasitif kuplajla yap\u0131land\u0131r\u0131labilir.<\/p>\n

Testlerde bu tasar\u0131m i\u00e7in kapasitif besleme k\u00f6pr\u00fcs\u00fc tercih edildi. Kondansat\u00f6r de\u011ferleri, Pisagorcu alt\u0131n orandan esinlenen ili\u015fkiler kullan\u0131larak hesapland\u0131: \u03c6 = 1,618<\/strong>. Ama\u00e7, se\u00e7ilen kapasitans de\u011ferleri aras\u0131nda orant\u0131l\u0131 farklar olu\u015fturmakt\u0131.<\/p>\n

Bile\u015fen se\u00e7imi de \u00f6nemliydi. Standart seramik SMD kondansat\u00f6rler bu tasar\u0131m ba\u011flam\u0131nda istenen performans\u0131 g\u00f6stermedi\u011finden, geli\u015ftirme s\u0131ras\u0131nda y\u00fcksek kaliteli RF kondansat\u00f6rleri ve mika dielektrikli kondansat\u00f6rler tercih edildi.<\/p>\n

Yak\u0131n alanda faz etkile\u015fimi<\/h2>\n

Spiral faz dizili anten, yak\u0131n alan faz etkile\u015fimi kavram\u0131na g\u00f6re tasarlanm\u0131\u015ft\u0131r. Trinity Radionics terminolojisinde bu, birden \u00e7ok spiral katman\u0131n ve faz ili\u015fkilerinin odaklanm\u0131\u015f, skaler tarz\u0131 bir yay\u0131n alan\u0131 olu\u015fturacak bi\u00e7imde d\u00fczenlenmesi anlam\u0131na gelir.<\/p>\n

Ama\u00e7, radyonik \u00e7al\u0131\u015fma ve niyet yay\u0131n\u0131 i\u00e7in daha g\u00fc\u00e7l\u00fc ve daha e\u015fevreli bir yay\u0131n yap\u0131s\u0131d\u0131r.<\/p>\n

Tasar\u0131m ve geli\u015ftirme ara\u00e7lar\u0131<\/h2>\n

Anten tasar\u0131m s\u00fcrecinde matematiksel hesaplamalar, RF tasar\u0131m kavramlar\u0131, PCB yerle\u015fiminin geli\u015ftirilmesi ve pratik deneyler birlikte kullan\u0131ld\u0131.<\/p>\n
