Abstract:

With the development of material science,the light,portable and foldable reflector antenna has been gradually popularized and replaced the metal reflector antenna of solid surface on some special occasions.In this paper,MOM and PO methods are used to design an offset reflector antenna with a gain of over 42 dB.The antenna is made from silver fabric,which has good electromagnetic wave reflection,on the basis of an umbrella structure.It provides a good method for the development of light,small,potable reflector antennas.

Key words: antenna;reflector;umbrella structure of the antenna
