1. A mobile phone antenna, comprising:
- a first conductive radiation element that is formed in a sheet metal conductor and resonates at a predetermined resonance frequency;
a second conductive radiation element that is formed in the sheet metal conductor and resonates at the predetermined resonance frequency; and
a ground that is connected through a conductive ground connector with said second conductive radiation element;
wherein said ground is placed such that said ground is not opposed to said first and second conductive radiation elements, and wherein said second conductive radiation element functions as a ground, wherein said ground includes;
a first ground that is connected through said conductive ground connector with said second conductive radiation element; and
a second ground that is connected through a conductive inter-ground connector with said first ground, said second ground being capable of rotating in the range of a predetermined angle from a position that said second ground faces in parallel to said first ground, wherein said conductive inter-ground connector is positioned under said second conductive radiation element when said second ground rotates by said predetermined angle, wherein said conductive inter-around connector has a first bend portion at a first end thereof, a straight middle portion, and a second bend portion at a second end thereof, and wherein the first bend portion is directly connected to said first around and said second bend portion is directly connected to said second ground.
