Design of beam steering planar monopole antenna mounted on LEO small satellite

In this study, shows the possibility of fabricating an antenna with simple structure at low cost. We also designed a planar monopole antenna for satellite - satellite link and satellite - terrestrial link for LEO small satellites that can smoothly change the beam steering angle. As a result, the link-budget was satisfied with a -10dB bandwidth of 13MHz and a gain of 3.17 dBi(satellite-satellite at θ= 70°) at a center frequency of 436.5 MHz.
