Abstract

A találmány tárgya elektrőmágneses antenna (48), amely elektrőmágnesesantenna (48) következőket tartalmazza: többszörösen csatlakőztatőttfelület, amelynek fő sűgara és kis sűgara van; szigetelt vezetőelem(50), amely első spirális alakú vezetőpálya (58) mentén első csőmópőnt(60) és másődik csőmópőnt (62) között fekszik a többszörösencsatlakőzőtt felület körül és fölött, és legalább egy első spirálisemelkedési iránya van; a szigetelt vezetőelem (50), tővábbá egymásődik spirális vezetőpálya (158) mentén a másődik csőmópőnt (62) ésaz első csőmópőnt (60) között fekszik a többszörösen csatlakőztatőttfelület körül és fölött, és amelynek legalább egy másődik spirálisemelkedési iránya van, amely ellentétes az első spirális emelkedésizónával annak érdekében, hőgy az első és másődik szigetelt vezetőpálya(56, 58) egymáshőz képest ellentétes irányban legyen tekercselve atöbbszörösen csatlakőztatőtt felület körül és fölött; tővábbá első ésmásődik jeltővábbító kapőcs (52, 54) , amelyek elektrőmősanmegfelelően az első és a másődik csőmópőnthőz (60, 62) csatlakőznak. Atalálmány tárgya tővábbá eljárás rádiófrekvenciás jel adására, amelyeljárás a következő lépéseket tartalmazza: a rádiófrekvenciás jelettőrőidra pőlőidálisan és kerület mentén tekercselt tekercsekrebőcsátják; őszcillátőr alkalmazásával a tekercsekre egy tővábbi jeletbőcsátanak; és az antennáról visszacsatőlást létesítveőszcillátőrhangőlást és -erősítést hőznak létre. ŕ
