介绍了平方公里阵列(SKA)望远镜[1]低频天线单元的电磁建模与测试。这些元件覆盖70至450 MHz的频段,由对数周期偶极子阵列(LPDA)模型组成,它们的设计是为了在距离天顶+/- 45度的区域内获得最大的灵敏度。一个16元阵列(AAVS0 -孔径阵列验证系统)已经在英国剑桥的洛德桥建成,并正在进行测试,以验证天线元件和前端的电磁特性。我们专注于这些元素的建模,并比较模拟和测量数据的仿真软件验证。
The electromagnetic modeling and testing is presented for antenna elements devoted to the low frequency band of the Square Kilometre Array (SKA) telescope [1]. Covering a band from 70 to 450 MHz, these elements consist on a log-periodic dipole array (LPDA) model and they have been designed for maximum sensitivity across the band in the region +/- 45 degrees from zenith. A 16-element array (AAVS0 - Aperture Array Verification System 0) has been built in Lords Bridge, Cambridge, UK, and it is being tested to validate the electromagnetic properties of the antenna elements and front-end. We focus on the modeling of these elements and compare simulated and measured data for simulation software validation.
