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 [24] 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 [25].
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..

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 antennas.
