When compared to the classical omnidirectional
ADE configuration, the aperture uniform illumination rises the side lobes close to the main beam, and, due to the increase of the density of rays toward the main reflector edge (see Figure 5), it increases the main reflector spillover and rises the side lobe level behind the main reflector, particularly at 140[degrees] < [theta] < 180[degrees] (see Figure 7).
One other important issue to be noticed in the design to provide omnidirectional
(or low gain variation) is that the slots should have not only physical circular symmetry on the circular waveguide but also the fields on the slots should have circular symmetry.
In contrast, more recently, the systems that provide omnidirectional
visual information  have gained popularity thanks, mainly, to the great quantity of information they provide the robot with, as they usually have a field of view of 360 deg around the robot .
When the ith omnidirectional
wheel's central speed is mapped to Cartesian coordinate system, then
In Section 2, the kinematic model of the omnidirectional
wheeled mobile platform is presented in Cartesian-coordinates.
The structure is assumed to be excited by an omnidirectional
source, such as a vertical electric dipole (VED), a vertical magnetic dipole (VMD), a horizontal electric ring, etc..
10 Instrument Landing Systems (ILS) and 6 Doppler VHF Omnidirectional
Radio Range (DVOR)
According to Zimmer Spine, all Virage system polyaxial dual-lead screws incorporate 360-degree omnidirectional
extreme-angle screw technology, allowing for 112 degrees of conical range of motion and simplifying rod alignment.
Intralox won the Best New Innovation award for the Omnidirectional
Sorter, while Product Protector took Best Innovation of an Existing Product.
CAISIs can be deployed to establish connectivity using a combination of grid, dual-band, and omnidirectional
