Abstract :
In this paper, we describe a vehicle-mounted satellite antenna for receiving satellite TV while the vehicle is in motion. Specifically, we discuss a slotted waveguide planar vehicle-mounted satellite antenna with simultaneous dual polarization states, which uses a hybrid electronic and mechanical steering mechanism, and is operable while the vehicle is in motion. The antenna (and electronics) has a small enough profile (less than 3 inches) that it can be embedded into the vehicle roof, such that it cannot be seen either inside or outside of the vehicle, i.e., it fits between the roof and the headliner. Experimental results for this antenna in a vehicle are presented.
