Abstract Here, the planar superstrate is Freezer Knob used to tailor the conical beam.In the applications of conical beam antenna, making a good balance between the wider coverage and the higher gain is always a challenge, while the planar superstrate provides the freedom of design.Through adjusting the parameters of the planar superstrate, it is p
Global Navigation Satellite System Real-time Kinematic (GNSS-RTK) is an indispensable source for the absolute positioning of autonomous systems.Unfortunately, the performance of the GNSS-RTK is significantly degraded in urban canyons, due to the notorious multipath and Non-Line-of-Sight (NLOS).On the contrary, LiDAR/inertial odometry (LIO) can prov
