Abstract


  • This paper studies the suitability of shorted patch and CPW-feed square slot

    antennas for CubeSat communications. To study the effect of the CubeSat body on the

    antennas performance, we have simulated both antennas in the High Frequency

    Structure Simulator (HFSS) with and without the CubeSat body. Compared to CPWfeed

    square slot antenna, the shorted patch antenna achieves higher gain and wider

    bandwidth. We have also re-dimensioned both antennas to shift their resonant

    frequencies to 2.45 GHz using Quasi Newton method in HFSS. This thus enables their

    use in the unlicensed ISM band. The repurposed shorted patch has smaller return loss;

    e.g., -27.5 dB (without CubeSat), higher gain; e.g., 5.3 dBi and wider bandwidth than

    the repurposed CPW-feed Square slot antenna. Lastly, further enhancement in the gain

    of re-dimensioned CPW-feed square slot antenna shows an increase of total gain from 2

    to 2.52 dB.
