On omnidirectional coverage with minimum number of circularly polarized patch antennas placed on minisatellites

On combine radiation properties of patch antenna cluster placed on small boxes

“…However, the same analysis shows that with use of four instead of six antenna elements, the hazard of encountering deep null in the combined radiation pattern may be considerably reduced. Calculated radiation patterns plotted in Figure 13 reveal small effect of phasing variations between three feed cables onto the combined pattern [6]. That phenomenon we usually observed with different placement of patch elements.…”

“…To perform experimental studies we developed three customized box models of metal sheets or of composite materials cladded with a copper foil (one model is shown in Fig. 1) [5], [6]. Radiation pattern plots in Fig.…”

A compact microstrip antenna with tapered peripheral slits for CubeSat RF Payloads at 436MHz: Miniaturization techniques, design & numerical results

“…Finally, several planar antennas were built to address the communication needs of European small satellite missions, such as the ESEO and SSETI-Express student orbiters, and the commercial SSTL [13] - [16]. The antennas are placed onboard much larger facets, since the orbiters are sized at 3 60 60 60cm × × , and they operate at higher frequencies (2.025 -2.400 and 8.450 GHz).…”

Development of S band antenna for Nanosatellite

“…Apart from a gain variation of 3 dBi, no other details are given. Furthermore, a low-profile, low-gain planar antenna at 2.4 GHz for a SSETI-Express mini-satellite of 60×60×70 cm 3 size was also proposed in literature [15]. Special emphasis is placed on achieving circular polarization and acceptably low axial ratio, so that controlled degeneration to elliptical polarization can be achieved.…”
