Abstract
A multi-band antenna with the broadband function is based upon a planar inverted-F antenna with two conductive arms and a ground. The two conductive arms extend from the ground near the two opposite ends of the ground. Two radiation plates of the two conductive arms extend toward each other. The multi-band antenna has a sufficient large band at high frequencies. Since the conductive arms are disposed close to the two ends of the ground, operations of bending the two conductive arms or soldering a feed wires are simpler and have a higher yield.
Claims8
A multi-band antenna comprising:
- a ground having a first end, a second end, a first elongated side and a second elongated side;
- a first conductive arm having a radiating plate and a connecting plate, the connecting plate of the first conductive arm connected to the first elongated side of the ground near the first end and extending toward the second end;
- a second conductive arm having a radiating plate and a connecting plate, the connecting plate of the second conductive arm connected to the second elongated side of the ground near the second end and extending toward the first end;
- and
- a coaxial feed wire having a central wire and an outer wire, the central wire electrically connected to the radiating plate of the first conductive arm, and the outer wire electrically connected to the ground;
- wherein the radiating plates of the first conductive arm and the second conductive arm are parallel to the ground.
