Abstract
A dual frequency antenna includes a first scythe-shaped arm and a second scythe-shaped arm. The first scythe-shaped arm is configured for operating in a first band. The second scythe-shaped arm is configured for operating in a second band and includes an inverted-T-shaped strip with a foot of the inverted-T-shaped strip connected to the second scythe-shaped arm. The first scythe-shaped arm is attached to the second scythe-shaped arm at an apex. A head of the inverted-T-shaped strip is closer to the apex than the foot. A communication system is also provided.
Claims20
A dual frequency antenna comprising:
- a first arm operating in a first band, the first arm having a first scythe-shaped structure;
- and
- a second arm operating in a second band, the second arm having a second scythe-shaped structure and an inverted-T-shaped strip with a foot connected to an end of the second scythe-shaped structure, the second scythe-shaped structure attached to the first scythe-shaped structure at an apex;
- wherein a head of the inverted-T-shaped strip is closer to the apex than the foot and an angle is defined by the first scythe-shaped structure and the second scythe-shaped structure at the apex.
A dual frequency antenna comprising:
- a first arm operating in a first band, and comprising a first scythe-shaped structure;
- and
- a second arm operating in a second band, and comprising a second scythe-shaped structure and an inverted-T-shaped strip, the first scythe-shaped structure and the second scythe-shaped structure extending from an apex and defining a triangle;
- wherein the inverted-T-shaped strip is inside the triangle, and a foot of the inverted-T-shaped strip is connected to the second scythe-shaped structure.
A communication system comprising:
- a dual frequency antenna for operating in a first band and a second band different from the first band, the dual frequency antenna comprising:
- a first arm operating in a first band, and comprising a first scythe-shaped structure;
- and
- a second arm operating in a second band, and comprising a second scythe-shaped structure and an inverted-T-shaped strip with a foot connected to the second sick-shaped structure, the second scythe-shaped structure attached to the first scythe-shaped structure at an apex;
- wherein a head of the inverted-T-shaped strip is closer to the apex than the foot and an angle is defined by the first scythe-shaped structure and the second scythe-shaped structure at the apex;
- and
- a processing module receiving signals from the dual frequency antenna and processing the signals.
