摘要
Abstract
The rocket⁃borne relay terminal has high requirements on transmitting antenna in terms of scanning speed and beam coverage.Phased array is a suitable alternative for that application due to its rapid and inertia⁃free beam steering ability.The paper intro⁃duces a design of rocket⁃borne circularly⁃polarized phased array with wide scan range. In the design of the array, circularly⁃polarized microstrip patch is selected as the radiating element and a conformal structure is used.The sequential rotation feeding is also implemen⁃ted.A prototype phased array is designed and fabricated following the procedure proposed.The test results show the antenna is able to cover ±60° in azimuth and ±45° in elevation.The antenna gain varies from 13.2 dBi to 17.2 dBi in the above scan range.The axial ratio in the main beam is better than 5.8 dB and HPBW is 20°to 40°. The specifications of the prototype satisfy the requirements on the transmitting antenna of relay terminal.关键词
