专利汇可以提供Antenna device专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain an antenna device used for the man-made satellite launching rocket featuring the reduced feeding loss and with no impairment of the reliability by using the ratching circulator. CONSTITUTION:Before head-opening and separation of fairing 3, the telemeter signal given from telemeter-transmitter device 14 goes toward terminal 11 of ratching circulator 9 to be radiated through fairing antenna 7. Fairing 3 is head-opened and separated at an appropriate time after the rocketlaunching, and pull-out coaxial connector 8a is pulled out to be thrown away along with antenna 7. Controller 13 operates simultaneously with head-opening of fairing 3 to invert the transmission direction of circulator 9, and thus the telemeter signal from transmitter device 14 goes toward terminal 12 of 9 to be radiated through telemeter antenna 4 via 4-distribution power divider 17.,下面是Antenna device专利的具体信息内容。
