Abstract
Official abstract text for this publication.
An optically controlled microwave antenna that reduces the optical power consumed by the antenna and to enable polarimetric detection an optically controlled microwave antenna comprises an antenna array and a feed for illuminating said antenna array with and/or receiving microwave radiation. The antenna array comprises a plurality of antenna elements each including a waveguide, two optically controllable semiconductor elements arranged within the waveguide in front of the light transmissive portion of the second end portion, 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 said semiconductor element for controlling its material properties, and a septum arranged within the waveguide in front of the light transmissive portion of the second end portion and separating said waveguide into two waveguide portions.
First claim
Opening claim text (preview).
The invention claimed is: 1. An optically controlled microwave antenna comprising: an antenna array comprising a plurality of antenna elements, each said antenna element including: a waveguide to guide 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 having a light transmissive portion formed in at least a part of the second end portion, two optically controll…
