This paper presents a novel wideband circularly polarized CPW-fed printed monopole antenna for CubeSat applications. An AMC reflector with 5× 5 -unit cells is used to increase antenna gain. The overall size of the antenna is 0.48λ 0 × 0.48λ 0 × 0.042λ 0 at the operating frequency of 8-GHz. The proposed printed monopole antenna provides a wide impedance bandwidth and a wide 3-dB axial ratio bandwidth. When comparing our proposed antenna to all designs, it is evident that the proposed printed monopole antenna offers several advantages. Firstly, it exhibits higher gain and a wider 3-dB axia...

In this paper, we propose a compact single-fed corner arc-truncated square patch antenna with T -diagonal slot and periodically defected ground (PDGS) plane for X band and mm-wave CubeSat applications. A square patch antenna printed on a grounded FR4 slab is used as the building block. Furthermore, its performance is enhanced in terms of impedance bandwidth by adding periodically circular slots in the ground plane to obtain ultra-wideband characteristics. Dual circular polarization, at two resonant frequencies of 10 and 25.6 GHz is achieved by loading the patch with a T-diagonal slot and trunc...

In this paper a high gain circular polarized microstrip patch antenna array for X-band CubeSat applications is presented. The array consists of 36 elements arranged in a square lattice of 6x6 presenting circular polarization with a -3dB axial ratio bandwidth of 3.8% at 10. 4GHz. The antenna array is printed on FR4 substrate to reduce the overall cost of the CubeSat while achieving a -10dB impedance bandwidth of 21%. Finally, the array is mounted on the top face of a 1U CubeSat providing a high gain of 20.1dB at 10. 4GHz with a -3dB gain bandwidth of 38.4%.
