Abstract
This paper intends to design a new feed of a parabolic receiving antenna system, to receive Himawari-8 satellite data at the Remote Sensing Ground Station. The traditional antenna design of a parabolic antenna system uses a horn antenna fed by a monopole. This paper proposes a horn antenna fed by a trapezoid microstrip patch, to get a higher gain antenna system. The gain of the inverted trapezoid microstrip patch antenna is about 7.6 dB at a frequency of 4.148 GHz. The combined gain of the microstrip patch antenna with the flared horn which is known as the feed antenna is 15.8 dB at a frequency of 4.148 GHz. The return loss value of the combined antenna has a frequency bandwidth from 4.023-4.212 GHz with a limit of -10 dB. The overall gain generated from the feed antenna and 2.4-meter parabolic reflector is around 34.9 dB at a frequency of 4.148 GHz.
