Satellite communication antennas commonly employ beamforming networks (BFN's) which hitherto have been realized with discrete components. This paper presents two alternative BFN technologies developed at Spar Aerospace, namely integrated waveguide and integrated TEM-line which advantageously replace the discrete component technology. The integrated feed concept is presented together with design examples...
Microwave components carrying medium or high powers in the space environment may suffer from multipactor breakdown. The resulting discharge can seriously affect the performance of communications equipment, so effective multipactor detection is essential in the development and qualification stages of flight hardware. This paper presents an extremely sensitive method of detection by means of a travelling...
