Abstract
The work aims to design a quasi-end-fire antenna that can support high data rate downlink communications for small satellites. This developed end-fire antenna uses a parallel-plate waveguide (PPW) launcher based on substrate integrated waveguide (SIW) technology that achieves power transfer to a grounded dielectric slab (GDS) by excitation of transverse magnetic (TM) surface waves (SWs) through a matching section realized by sub-wavelength patches. In particular, these SWs transfer from a T-junction SIW launcher to the GDS for end-fire radiation by a partially reflective screen made in one of the via sidewalls which has been designed using leaky-wave (LW) theory. This paper will firstly present the background information about small satellites and the challenges with antenna integration. Some theory is also discussed describing the design approach for the proposed antenna. After that, simulations and results of the SIW antenna, which is to operate at about 18 GHz, are reported. Applications of the quasi-end-fire antenna include broadcasting, planetary observations systems, and inter-satellite links.
