Detail
The design needs to balance electrical performance and mechanical reliability. Electrical challenges include signal loss and polarization purity optimization at high frequency bands, which can be improved by enhancing the isolation to over 35dB through improvements in the feed network (such as L-probe feed). Mechanical challenges involve wind resistance and temperature adaptability, requiring the use of high-strength materials (such as glass fiber reinforced plastic) and thermal compensation structures. For example, a certain model of antenna has increased its radiation efficiency to 85% by optimizing the shape of the reflector side wall, while also meeting the wind resistance requirement of 60m/s.
