Support structure for antenna, preparation method thereof, and use thereof

An antenna component, comprising:

• a secondary reflective surface,
• a feed tube,
• a hollow support connector having a first end and a second end,
• wherein the support structure is configured to be connected between the feed tube and the secondary reflective surface,
• wherein the support connector is made of a foamed material,
• wherein a size shrinkage rate of the support connector is less than or equal to 1% after the support connector is placed in an environment with a temperature of 70° C. to 100° C. and relative humidity of 50% to 95% for four days, and
• wherein the feed tube is connected at the first end, and the secondary reflective surface is connected as the second end.

An antenna, comprising:
