title = "Sidelobe Level Suppression and Scan-Loss Compensation in A Wide-Angular Scanning Linear Array Using Subarrays Amplitude Control",
abstract = "An improvement of the wide-angular scan-loss compensation (SLC) and sidelobe level (SLL) in a small linear array with 23 elements is discussed. The array integrates small subarrays with an optimized pattern for SLC, while the SLL suppression is obtained by using a combination of elements with phase steering only and elements with amplitude/phase control in the center. This combination leads to a less number of T/R module. When the antenna is scanned to ±60°, a maximum first and peak SLL (FSLL and PSLL) of -15.1 dB are obtained. In addition, a -4.6 scan-loss is obtained, it means that the SLC is 2.4 dB with a Cavity-backed U-slotted Patch (CUP) antenna. These performance results are very attractive in particular for a small linear array with wide angular scanning capability.",
