A 3D directional antenna for S band small satellite communication system

摘要

In this paper, an S-band three-dimensional antenna for small satellite application has been presented. Folding the radiating element, use of shorting wall and ground reflector etc. different optimization techniques have been obtained to achieve a desirable performance from the antenna. Finally, the proposed antenna successfully obtained operating bands at 2-2.27 GHz and 2.53-3.58 GHz. The peak gain of the antenna is up to 4dB. The simple design structure make the antenna easily fabricable for mass production from a single copper sheet using stamping metal sheet method or 3D printing technology. The design and analysis of the antenna have been performed using electromagnetic simulation software. S band operation, directional radiation property, up to 4dB realized gain over the operating frequency make the antenna a candidate to be applied for communication system in small satellites.
