English abstract:
A beam- and polarisation-reconfigurable substrate integrated waveguide (SIW) ring-slot antenna array is proposed in
this study. The 2 × 2 ring-slot antenna array can generate beams in four different directions in two orthogonal linear polarisations(LPs). This is achieved by a feeding network consisting of four 90∘ SIW 3 dB couplers arranged in a multilayer structure for a
compact antenna size of 131.6 mm × 65.8 mm × 4.9 mm. The antenna elements´ LP plane is controlled by PIN diodes, switched
by a DC bias network integrated on the antenna substrate. The proposed antenna array is designed for the 5.8 GHz industrial,scientific and medical (ISM) frequency band and verified by measurements. Experimental results validate good impedancematching over the entire frequency band as well as the beam and polarisation reconfigurability.
