Title:
BROADBAND BUILT-IN ANTENNA USING DOUBLE ELECTROMAGNETIC COUPLING
Document Type and Number:
WIPO Patent Application WO/2011/046368
Kind Code:
A2
Abstract:
Disclosed is a broadband built-in antenna using double electromagnetic coupling. The disclosed antenna comprises a first conductive member electrically connected to a feeding point; a second conductive member which is spaced apart by a predetermined distance from at least one portion of the first conductive member such that the second conductive member is firstly electromagnetically coupled to the at least one portion of the first conductive member, wherein the second conductive member is maintained at a floating state in which the second conductive member is not coupled to earth and to the feeding point; a third conductive member which is spaced apart by a predetermined distance from the second conductive member such that the third conductive member is secondly electromagnetically coupled to the second conductive member, wherein the third conductive member is electrically connected to earth; and a fourth conductive member extended from the third conductive member to radiate an RF signal. The disclosed antenna has advantages in that broadband characteristics can be ensured within a limited size.
