Elevated Vehicle Antenna Assembly for Signal Shadowing

The patent extends the antenna array into the third dimension by stacking multiple dipole antennas vertically. This vertical dimension allows the antenna system to radiate electromagnetic energy above the vehicle surface, creating a direct path signal that bypasses the shadowing and scattering effects caused by the vehicle body, thereby improving signal strength in close proximity to the vehicle.

The antenna system is divided into multiple segmented dipole antennas stacked vertically. Each dipole antenna element contributes to the overall radiation pattern, and their combined effect creates a more robust signal that overcomes the shadowing effect. The segmentation allows the system to achieve better coverage without requiring a single complex antenna structure.

The vertically stacked dipole antenna array serves multiple functions: it provides omnidirectional radiation coverage, creates direct path signals above the vehicle surface, and overcomes shadowing effects. This multi-functionality is achieved through a relatively simple repetitive structure of identical dipole elements, which simplifies manufacturing compared to designing a completely new antenna type.

The patent changes the spatial parameter of the antenna system by stacking dipoles vertically at specific intervals. This parameter change (vertical spacing) is optimized to create the desired radiation pattern and direct path coverage. The use of standard dipole elements with controlled spacing allows for straightforward manufacturing while achieving the required signal coverage improvements.
