Title: | Preliminary Analysis of the Effects of the Ground Plane on the Element Patterns of SKA1-Low | Authors: | BOLLI, Pietro Bercigli M. DI NINNI, PAOLA Labate M.G. Virone G. |
Issue Date: | 2020 | Volume: | 2020 14th European Conference on Antennas and Propagation (EuCAP) | First Page: | 1 | Abstract: | Each station of the SKA1-Low radio telescope is composed by 256 dual-polarized log-periodic antennas deployed over a metallic ground plane with 42 m diameter. This station is usually modelled in EM simulators by considering an infinite ground plane, which drastically reduces the computational time. This contribution shows that a finite ground plane can bring to quite significant differences in some embedded element patterns with respect to the infinite ground plane case. Furthermore, we show the impact on the antenna pattern of different dielectric media surrounding the finite ground plane. For instance, at 50 MHz the maximum of the antenna gain decreases by 5% for the terrain with 10% moisture level. | Conference Name: | 2020 14th European Conference on Antennas and Propagation (EuCAP) | Conference Place: | Copenhagen, Denmark | Conference Date: | 15-20 March, 2020 | URI: | http://hdl.handle.net/20.500.12386/31381 | URL: | https://ieeexplore.ieee.org/document/9135350 | ISBN: | 9788831299008 9781728137124 |
