N2 - Internet of Remote Things can be facilitated by network of CubeSats to connect communication nodes located at remote areas. Due to CubeSat's small dimension, it is challenging to produce antenna with high gain, low axial-ratio, and wide bandwidth both in impedance and axial ratio. This paper presents a circularly polarized microstrip array optimized for a side of 1U CubeSat (10 cm x 10 cm). An array of 4x4 corner-truncated microstrip patches is constructed on 0.79mm-thick RT5870. Sequential-rotation technique is employed as the array's feeding network. Electromagnetic simulations show that the antenna design can produce a peak realized gain of 13.34 dBic (left-hand) at 5.8 GHz, realized gain above 10.34 dBic at 5.08 GHz to 6.45 GHz, axial ratio below 3 dB at 5.45 GHz to 6.29 GHz, and reflection coefficient below -10 dB at 5.34 GHz to 6.21 GHz.
