摘要：
This paper presents some recent development work on planar waveguide array antennas for 5G backhaul and satellite communications. Several design examples are provided, focusing on the design challenges of side-lobe suppression, dual-band dual-polarisation, and beam scanning. Aperture rotation and polarization rotation are two approaches used for side-lobe suppression. Their trade-off with cross polarization discrimination has been discussed. Examples of dual-polarisation wideband or dual-band arrays are given. Finally, variable inclination continuous transverse stub (ViCTS) antenna is discussed as a potential cost-effective solution to phase arrays in satellite communications. All the presented antennas are based on hollow waveguides constructed using multiple layers.
