A low-profile user terminal antenna for mobile bi-directional Ka-band satellite communications
This paper presents a low-profile user-terminal antenna for mobile bi-directional Ka-band satellite communication networks for emergency scenarios. We have devised an antenna with a circularly polarised radiation pattern and dual-band capability, which addresses a hybrid tracking. The principle of operation of a rectangular antenna panel applying a dual-band partially reflective surface (PRS) of 60 mm by 200 mm was manufactured and successfully verified. This publication describes the design of the panel and analyses measurement results. Furthermore, our first low-profile antenna demonstrator is presented, intended to be evaluated at a testbed for satellite communications in Ilmenau.
