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; and
- a plurality of circulators mounted on said dielectric substrate and connected in series to said antenna elements, respectively,
- wherein said circulators are arranged in pairs of adjacent circulators, said circulators in each of the pairs being arranged such that DC magnetic fields in mutually opposite directions are applied to the circulators, respectfully, for rotating signals in mutually opposite directions in the circulators.
- 2. An antenna device according to claim 1, further comprising a scanning control circuit for switching the antenna elements in a time-sharing fashion.
