A Reflector Type 3D Triband Directional Antenna for CubeSat Applications

In this paper, a three-dimensional antenna for CubeSat applications is proposed. The proposed antenna achieved unidirectional radiation characteristics at its operating bands. Different optimization techniques such as a folded radiating structure, shorting wall and ground reflector are used to achieve a standard performance from the antenna. The proposed antenna successfully achieved three operating bands: 1.55–1.67 GHz, 1.99–2.27 GHz and 2.53–3.58 GHz. A front-to-back ratio of 15 authenticates its directive radiation pattern. The proposed antenna achieved a peak gain of 4 dB. The antenna has been designed in such a way that it can be fabricated for mass production easily from a single copper sheet using folding technique. Computer Simulation Technology (CST) Microwave Studio software has been used to design and perform the simulation work. A lower operating band, unidirectional radiation characteristics, and a satisfactory amount of gain over the operating frequency make the antenna a candidate to be used in CubeSats for space communication purposes.
