| 发明名称 | Optically controlled microwave antenna | ||
| 摘要 | An optically controlled microwave antenna that reduces optical power consumed by the antenna. The optically controlled microwave antenna includes an antenna array including plural antenna elements and a feed for illuminating the antenna array with and/or receiving microwave radiation of the operating frequency from the antenna array to transmit and/or receive microwave radiation. An antenna element includes a waveguide, an optically controllable semiconductor element arranged within the waveguide in front of a light transmissive portion of a second end portion, the semiconductor element changing its material properties under control of incident light, and a controllable light source arranged at or close to the light transmissive portion of the second end portion for projecting a controlled light beam onto the semiconductor element for controlling its material properties, in particular its reflectivity. | ||

| 主权项 | 1. An optically controlled microwave antenna comprising: i) an antenna array comprising a plurality of antenna elements, an antenna element comprising: a waveguide for guiding microwave radiation at an operating frequency between a first open end portion and a second end portion arranged opposite the first end portion, said second end portion including a light transmissive portion formed in at least a part of the second end portion,an optically controllable semiconductor element arranged within the waveguide in front of the light transmissive portion of the second end portion, said semiconductor element changing its material properties, its reflectivity of microwave radiation of the operating frequency, under control of incident light, anda controllable light source arranged at or close to the light transmissive portion of the second end portion for projecting a controlled light beam onto said semiconductor element for controlling its material properties, or its reflectivity; and ii) a feed for illuminating said antenna array with and/or receiving microwave radiation of the operating frequency from said antenna array to transmit and/or receive microwave radiation. | ||
