This work presents the advances in the development of two innovative flat array antennas for Ku-band mobile satellite terminals.
The first antenna is specifically conceived for double-deck trains to allow a bi-directional high data rate satellite link.
The available circular surface (diameter 80 cm) integrates both a transmitting and a receiving section, operating in orthogonal linear polarizations.
The TX frequency range is fully covered while the RX bandwidth is around 1 GHz arbitrarily allocated on the DVB range depending on requirements.
The beam is steered in elevation through a phased array architecture not employing costly phase shifters, while the steering in azimuth is mechanical.
Active BFNs allow excellent performance in terms of EIRP and G/T, maintaining extremely low profile.
High antenna efficiency and low fabrication cost are ensured by the employment of innovative SIW (Substrate Integrated Waveguide) structures.
The second antenna, receiving-only, is designed for radio/video streaming services in mobile environment.
Full DVB coverage is achieved thanks to cavity-backed patches operating in double linear polarization.
Two independent broadband active BFNs allow simultaneous reception of both polarizations with full tracking capabilities and a squintless beam steering from 20∘ to 60∘ in elevation.
A minimum gain of 20 dBi and G/T >−3 dB/K∘ are achieved, while maintaining extremely compact size and flat profile.
In the design of both antennas fabrication cost is considered as a driving factor, yet providing high performance with a flat profile and thus resulting in a great commercial potentiality.
