- Abstract
Deep space exploration vehicles require real-time vehicle-earth communication along entire flight.Several existing types of low gain antennas for vehicle-earth communication are introduced.A new approach of combining the open-end waveguide with parasitic elements is presented.By diverse combination of waveguide dimension and the shapes of parasitic elements,a variety of shaped radiation pattern is available which realize vehicle-earth communication at different flight attitude.Employing this method,the low gain antenna for Yinghuo-1 mars exploration vehicle and low gain antenna for Chang’e-3 lunar rover are designed,which both meet their respective radiation pattern requirements.
