Mobile Satellite TV Antenna Tips

One of the highlights of the recent CES in Las Vegas is a new antenna system for Delphi Automotive, which makes it possible to follow a geo-stationary satellite from a moving vehicle.
Delphi said the launch if there are currently, military and other vehicles that use geo-stationary technology satellite with large radomes, they do not exist in low-profile form or alteration without the contour of a vehicle.

A Delphi vehicle demonstration showed the antenna technology fully integrated into the roof of an SUV. The antenna is thin enough to hold between the roof and inside the pavilion. The vehicle has several 7-inch television screens, radio frequency (RF) headphones for rear passengers. Each of the positions of passengers could choose between satellite television, DVD and video games.
"There are probably not a lot of consumers or producers who accept traditional antennas sprouting from the roof of their vehicles," said Dr. Dick Lind, director of advanced engineering at Delphi Electronics & Safety. "Our solution was to integrate the antenna system in the roof of the vehicle, without affecting the pitch, safety or aerodynamics," he added.
Since existing geo-stationary satellites are intended to be received by fixed platforms, Delphi has had to design an antenna system that is fully rotatable in horizontal plane and the constant elevation of the path of the satellite vehicle guidance and behavioral change.

The mechanical movement of the antenna associated with beam steering does not add noticeable noise in the passenger compartment or electromagnetic interference with other vehicle systems.
"After several years of development, we are very pleased to have a system that we believe will be trading in the coming years," said Lind. Delphi has worked with motia, a semiconductor company focused on the development of smart antennas for wireless systems.
