Abstract
Provided is a plasma antenna. The plasma antenna includes a radiation portion formed by stacking a plurality of radiation disks generating plasma based on provided energy and radiating a signal using the generated plasma, an energy generation portion configured to provide the energy to at least one of the plurality of radiation disks, and a signal transmission portion configured to provide the signal to the at least one radiation disk provided with the energy. Therefore, it is possible to support multiple frequency bands.
Claims8
A plasma antenna, comprising:
- a first disk pair comprising a first disk and a second disk;
- a second disk pair disposed under the first disk pair and comprising a third disk and a fourth disk;
- an energy generator configured to provide energy to at least one of the first to fourth disks;
- a signal transmitter configured to transmit a signal to the at least one of the first to fourth disks;
- and
- at least one plasma feed interposed between a first surface and a second surface of each of the first to fourth disks,
- wherein the first surface comprises a first conductive area, and the second surface faces the first surface and comprises a second conductive area, and
- wherein the first disk and the second disk comprise an identical diameter, the third disk and the fourth disk comprise an identical diameter, the first disk and the third disk comprise a different diameter, the first disk and the second disk comprise a different height, and the third disk and the fourth disk comprise a different height.
