چکیده
A wideband circularly polarized antenna based on the substrate integrated waveguide (SIW) is investigated and presented for mobile satellite applications. Initially, a rectangular-slot etched top layer of SIW cavity. truncated patch from one corner (top left) loaded inside slot to obtain two pairs orthogonal degenerate modes TE130/TE310 TE230/TE320. This truncated-corner helps bring closer circular polarization. Further, rotated incorporated enhance polarization bandwidth. The exhibits relative impedance bandwidth 20% (10.87–3.275 GHz) an axial ratio 11.50–12.26 GHz (6.4%). broadside radiation characteristics are achieved with peak gain 6.3dBic 7.0dBic at working frequencies 11.5 12.0 respectively.
