PLANAR INVERTED F-TYPE INTERNAL ANTENNA USING ELECTROMAGNETIC COUPLING FEEDING METHOD

摘要

The present invention discloses a planer inverter F internal antenna using an electromagnetic coupling feeding method, which improves the antenna performance as well as miniaturizes the antenna size by installing a feeder line having a predetermined length and a width and spaced at a predetermined distance from radiation elements on a PCB and indirectly supplying energy to the radiation elements from the feeder line by electromagnetic coupling. The antenna is provided with a laminate structure formed of a feeder line having a predetermined shape curved perpendicular at a predetermined height from a break point of a PCB, a radiation element extended in one direction on the upper end surface of a short circuit pin (or short circuit plate) having a predetermined height from the break point of the PCB, being spaced upwardly of the feeder line at a predetermined interval, a first dielectric element for providing an electromagnetic gap is filled between the feeder line and the PCB, and a second dielectric element for providing an electromagnetic gap is filled between the feeder line and the first radiation element.
