| 摘要 |
The invention relates to an electromagnetic wave receiver comprising a dielectric resonator antenna and to application in a receiver with a phased array antenna. The receiver comprises a dielectric resonator antenna (2) and a circuit (4) for processing signals delivered by the antenna. The antenna comprises a dielectric substrate (6), a ground plane (8), a dielectric resonator (10) and 1st to 4th probes (12 to 18) placed, in this order, at 90o to one another, in contact with the resonator. The circuit comprises an elementary circuit (38), connected to the 1st and 3rd probes, and another elementary circuit (36), connected to the 2nd and 4th probes. The ground plane (8) is formed on the first side of the substrate (6); the dielectric resonator (10) is located on the ground plane (8); the dielectric resonator antenna (2) furthermore comprises four electrically conductive lines (20, 22, 24, 26) located on the second side of the substrate (6) and respectively connected to the four probes (12, 14, 16, 18) through holes (28, 30, 32, 34) passing through the substrate and the ground plane; and, the elementary electronic circuits are connected to the probes by way of the electrically conductive lines. |
