I had a few questions regarding Sentinel-1 Antenna design, I would be glad if anyone could help me out.
The questions are as follows:
1. What are the dimensions of a single sub-array in the Sentinel-1 antenna, and how many patches does it contain?
2. How many sub-arrays are present in the entire antenna?
3. Additionally, what are the material properties used in the construction of the antenna?
Thanks in advance.
