What material are usually made of antennas?
For antennas, the stronger the conductivity of the metal surface, the better. We can see gold on the antenna on the satellite. Some microstrip antennas require silver plating. The metal cavity of the antenna is silver-plated. Basic.
From an economic and benefit point of view, aluminum tubes are mostly used, but the vibrator is connected to the wire with copper or silver plating, and copper is usually used for wire type and microstrip.
The connector parts of the glue stick antenna are usually gold-plated.
