Abstract
Official abstract text for this publication.
By providing a radiator configuration circuit and a feeding circuit each having a simple structure, a ground radiation antenna having a more simplified fabrication process as well as a remarkably reduced fabrication cost is provided herein. Additionally, a ground radiation antenna having an excellent radiation performance, even when one side of a mobile communication terminal is covered with a conductive substance, such as an LCD panel, is also provided herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A ground radiation antenna for a mobile terminal, the ground radiation antenna being formed on a PCB (Printed Circuit Board) having a ground substrate, the ground radiation antenna comprising: a radiator configuration circuit including first, second and third conductive lines, wherein the first and second conductive lines are perpendicularly positioned on the PCB and lower ends of the first and second conductive lines are connected to the ground substrate, and the third conductive line is formed on a cover of the mobile terminal, wherein when the cover is coupled to the mobile terminal, the third conductive line is electrically connected to upper ends of the first and second conductive lines, respectively; and a feeding circuit including a fourth conductive line formed on the PCB, wherein the feeding circuit includes a feeding point receiving an RF signal that is to be radiated. 2. The ground radiation antenna of claim 1 , wherein the third conductive line is formed of a conduction line pattern on one side of the cover of the mobile terminal. 3. The ground radiation antenna of claim 1 , wherein the first and second conductive lines are formed of pillar-shaped connection lines. 4. The ground radiation antenna of claim 1 , wherein the radiator configuration circuit includes a lumped circuit element. 5. The ground radiation antenna of claim 1 , wherein the lumped circuit element is formed on the PCB.
