N PORT FEEDING SYSTEM USING A SLOW WAVE STRUCTURE AND FEEDING DEVICE INCLUDED IN THE SAME CAPABLE OF DISTRIBUTING INPUT POWER TO N PORTS

摘要

PURPOSE: An N port feeding system using a slow wave structure and a feeding device include in the same are provided to reduce the size of an antenna using a feeding system by electrically connecting fist patterns with a slow wave structure to a third pattern of a linear type using second patterns for supplying input power to N ports. ;CONSTITUTION: A feeding system comprises a first substrate(210), a first pattern, a second substrate(212), and a second pattern(216). The first pattern that is a conductor is arranged on the first substrate. The second substrate is separated from the first substrate. The second pattern that is a conductor is arranged on the second substrate. The first pattern is electrically connected to the second pattern. The first pattern or second pattern includes a slow wave structure.;COPYRIGHT KIPO 2011
