Claims
- 1. An antenna device comprising:a dielectric substrate; an array of antenna elements mounted on said dielectric substrate, each of said antenna elements comprising a plurality of patches interconnected in a direction transverse to said array, said antenna elements being divided into two respective interdigitated groups wherein said respective groups of antenna elements are arranged in opposite directions that are 180 degrees apart from one another; and a plurality of circulators mounted on said dielectric substrate and connected respectively in series to said antenna elements.
- 2. An antenna device, comprising:a dielectric substrate; an array of antenna elements mounted on said dielectric substrate, each of said antenna elements comprising a plurality of patches interconnected in a direction transverse to said array; and a plurality of switches connected respectively to said antenna elements and being configured to enable transmission and reception by said respective antenna elements, wherein said switches are coupled to a control circuit and controlled in a time-sharing manner.
- 3. The antenna device of claim 2, wherein said switches comprise MMICs.
- 4. The antenna device of claim 2, wherein said switches comprise a plurality of FETs.
- 5. The antenna device of claim 2, wherein said switches comprise an amplifier.
- 6. An antenna device, comprising:a dielectric substrate; an array of antenna elements mounted on said dielectric substrate, each antenna element comprising at least one patch connected in a direction transverse to said array; a plurality of circulators mounted on said dielectric substrate and connected in series to said antenna elements, respectively; a plurality of amplifier switches connected to said circulators, each amplifier switch amplifying and providing switching for each antenna element.
- 7. An antenna device, comprising:a dielectric substrate: an array of antenna elements mounted on said dielectric substrate, each of said antenna elements comprising a plurality of patches interconnected in a direction transverse to said array; and a plurality of selective amplifiers connected to each of said antenna elements, each of said selective amplifiers transmitting a signal to said antenna elements or a selecting signal received by said antenna elements, wherein said plurality of selective amplifiers is controlled in a time-sharing manner.
- 8. The antenna device according to claim 7, wherein said plurality of selective amplifiers comprise MMICs.
- 9. An antenna device, comprising:a dielectric substrate; an array of antenna elements mounted on said dielectric substrate, each antenna element comprising at least one patch connected in a direction transverse to said array; and a plurality of selective amplifiers connected to each of said antenna elements, each of said selective amplifiers transmitting a signal to said antenna elements or selecting signal received by said antenna elements, wherein said plurality of selective amplifiers is controlled in time-sharing manner.
