The antenna system of Mars-rover

The paper describes two variants of antenna system construction for a Mars-rover intended for application in the structure of an onboard radio complex. It provides for receiving commands and transmitting information in C-frequency band. The first variant uses a parabolic reflector antenna with an electromechanical drive which ensures program guidance in extreme conditions. In the second variant, there is applied a slotted waveguide array with electronic control on the elevation coordinate
