The key features of a launcher antenna are specifically designed to meet the unique requirements of the launch phase of a space mission. These antennas possess several essential characteristics:
1.    Mechanical robustness: Launcher antennas must be designed to withstand the extreme mechanical vibrations and shocks experienced during launch. They need to be structurally resistant to high levels of acceleration.
2.    Thermal management: Launchers experience rapid temperature changes during ascent and descent. The antennas should be designed to handle these thermal variations and maintain optimal performance across a wide temperature range.
3.    Frequency Bands: Launcher antennas are optimized for specific frequency bands commonly used in launch operations, such as S-band, C-band, or GNSS bands. They are engineered to efficiently transmit and receive signals within these frequency ranges, ensuring reliable and uninterrupted communication during the launch.
4.    Ground-Based Operations: Launcher antennas are typically designed for ground-based operations and are installed on launchers. They are strategically positioned to establish reliable communication links with the ground station throughout the ascent phase, ensuring continuous monitoring and control.
