A mm-wave multiple-beam phased array breadboard for GEO-LEO inter-satellite links

This paper presents a prototype of a V band multiple-beam phased array, which is to be used on a GEO satellite as receiving antenna for GEO-LEO inter-satellite links. This antenna is capable of radiating four independent scan beams to support simultaneous data links between the GEO platform and four LEO satellites. Relevant measures have been introduced to reduce gross weight and power consumption of the RF payload. Experimental results of this breadboard meet the initial design requirements.
