140 GHz Planar Gap Waveguide Array Antenna for Line of Sight (LOS) MIMO Backhaul Links
12th European Conference on Antennas and Propagation (EuCAP 2018), 2018This paper presents a 140 GHz planar antenna array based on gap waveguide technology to be used in next generation backhauling links. Each antenna element in the bigger 3D-array is considered to have about 30dBi gain and each antenna element consists of several metal layers such as the cavity backed radiation layer and a corporate feed network layer ...

An Analysis of Line of Sight (LoS) in Mobile Ad hoc Networks by varying Impairments
2019 10th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2019The era of multimedia communication is a major part and partial of each and every user life each task now depends very much on the internet. We believe that line-of-sight is the biggest problem many are facing. In particular, the problem of mobile station tracking at various base stations is considered.

Cooperative Line-of-Sight (LOS) Based Control for Moving-Center Formation Flight of Multi Vehicles
2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC), 2018This note investigates the problem of moving-center formation of multi vehicles, such that the controlled vehicles orbit around a center moving with time-varying radius along the common circle, or move along the same straight line like geese in V formation.

ABSTRACT The techonology of LOS stabilization is widely appli cated in moving carrier photoelectric systems such as shipborne, airborne and so on. In application situations with compact structure, such as LOS stabilization system of unmanned aerial vehicle, LOS st abilization based on reflector is adopted, and the detector is installed on the carrier ...

2018 IEEE/MTT-S International Microwave Symposium - IMS, 2018
This submission describes phased-array antenna (PAA) development efforts in mobile communications and sensor applications at Ku-band and higher. The application of heterogeneous integration to a phased-array beyond the integrated circuitry and electronics allows a significant reduction of piece-parts and the number of suppliers as well as improving ...

2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat. No.04TH8754), 2005
The paper present the results of a multiple-input multiple-output (MIMO) channel capacity measurement experiment conducted in an indoor line-of-sight (LOS) office environment. Channel responses were taken systematically with varying distance in a static indoor environment. Results showed measurements with high received signal-to-noise ratio (SNR) and a

A Novel RF (XBee) and IR LoS (Line-of-Sight) Collaborative Vehicle-to-Vehicle Navigation Technique
SoutheastCon 2018, 2018Vehicle-to-Vehicle (V2V) communication has been under heavy development in the last decade. Most modern automobiles have a multitude of safety features and sensors that aid in the protection of the driver, however, most vehicles have no method or means to communicate with one another. With the recent advances in light communication, via Light-Fidelity (
