Performance Optimization of Unit-Cell Reflectarray Antenna for Future 5G Communications

Millimeter-Wave Mobile Communications Microstrip Antenna for 5G - A Future Antenna

In the present scenario, cellular service provider facing bandwidth shortage in conventional cellular system, and delivering high quality, low latency video and multimedia applications using 3G system which is on ground . The 4th Generation cellular networks are expected to be implemented in next few years. Here, we present the motivational approach for millimeter wave mobile communication ante...

Novel Element For Bnadwidth Improvement Of The Reflectarray Antenna

In this paper novel reflectarray antenna elements are proposed using aperture-coupled dielectric resonator antenna structures. Using these new structures, wide phase range and wide frequency bandwidth (up to 28.5%) with parallel and linear phase curves are obtained. In each case, an array consisting of 289 elements was simulated using the finite integration technique (FIT). The arrays exhibit 3...

Cooperative Distributed Antenna Transmission for 5G Mobile Communications Network

Reflectarray antennas for terahertz communications

Reflectarrays composed of resonant microstrip gold patches on a dielectric substrate are demonstrated for operation at terahertz frequencies. Based on the relation between the patch size and the reflection phase, a progressive phase distribution is implemented on the patch array to create a reflector able to deflect an incident beam towards a predefined angle off the specular direction. In orde...
