Investigating the Impact of Lunar Rover Structure and Lunar Surface Characteristics on Antenna Performance

Area of Science:

• Space exploration
• Radio frequency engineering
• Materials science

Background:

• Lunar missions require robust communication systems.
• The lunar environment presents unique challenges for antennas, including extreme temperatures and regolith interactions.
• Previous research has not fully addressed the combined effects of lunar regolith and rover structure on antenna parameters.

Purpose of the Study:

• To investigate the influence of lunar regolith properties and rover structural elements on antenna performance.
• To evaluate the effectiveness of different antenna types (sleeve dipole and all-metal patch) on the Rashid rover.
• To analyze the impact of thermal conditions and material composition on antenna functionality in the Atlas crater.

Main Methods:

• Conducting thermal analyses of the Atlas crater environment.
• Simulating antenna performance with varying lunar regolith conductivity and depth.
• Examining the effects of different thermal coatings and rover materials on antenna parameters.
• Assessing the performance of sleeve dipole and all-metal patch antennas.

Main Results:

• Lunar regolith characteristics significantly affect antenna performance.
• Rover material composition and thermal coatings influence antenna parameters.
• Temperatures in the Atlas crater can exceed 80°C, impacting antenna operation.
• Both antenna types showed susceptibility to environmental factors, with varying degrees.

Conclusions:

• Optimizing antenna design requires considering lunar regolith properties and rover materials.
• Effective thermal management is essential for reliable lunar communication.
• This research provides critical data for developing resilient communication systems for future lunar missions, including the Rashid rover.
