| Abstract | Phased array feed is a receiver technology that can make the radio telescope achieve continuous field of view coverage. Combined with the characteristics of reflector antenna, through focal field analysis and performance comparison under various designs, this paper presents the specific array design method of 1.25 GHz phased array feed. The final designed phased array feed can achieve three times the beam width of the telescope field of view at the working frequency of 1.25 GHz, the array size is 0.525m, the array element spacing is 0.437 times the wavelength, the array arrangement mode is hexagonal arrangement, and the final number of array elements is nineteen, of which the hexagonal subarray of 7 elements form one beam. Although the above array design parameters are not the optimal solution under the same conditions, the relevant steps can guide the array design of reflector antenna phased array feed, and also provide a reference for the later design of broadband and ultra wideband phased array feed array. |
