IMPROVEMENTS IN OR RELATING TO ANTENNA ARRAYS |
摘要 |
An antenna array comprises a dielectric image waveguide (3) acting as a feeder, which may be of the insular or inverted-strip type, in contact with a dielectric sheet (1). On the sheet (1) is located a plurality of strips (4) of metallizing extending outwards from the feeder-guide (3). The inner ends of the strips are located to couple with the feeder-guide and their outer ends act to radiate or receive most of the power. Preferably the mode propagated in the feeder-guide is an Emny mode higher than the fundamental, suitably the E21y mode. |
