Reconfigurable Antenna Multiple Access for 5G mmWave Systems

This paper aims to realize a new multiple access technique based on recently proposed millimeter-wave reconfigurable antenna architectures. To this end, first we show that integration of the existing reconfigurable antenna systems with the well-known non-orthogonal multiple access (NOMA) technique causes a significant degradation in sum rate due to the inevitable power division in reconfigurabl...

Study of Realistic Antenna Patterns in 5G mmWave Cellular Scenarios

Large antenna arrays and millimeter-wave (mmWave) frequencies have been attracting growing attention as possible candidates to meet the high requirements of future 5G mobile networks. In view of the large path loss attenuation in these bands, beamforming techniques that create a beam in the direction of the user equipment are essential to perform the transmission. For this purpose, in this pape...

Printed Monopole Antenna Technology for Wideband Applications

Broadband planar monopole antennas have attracted their candidature for wideband applications like WLAN, WiMAX, RADAR, Satellite etc. Eventhough planar monopole antennas have several advantages in terms of cost, compactness, conformality, simplicity they suffer from a major disadvantage of having very narrow bandwidth. Various planar configurations such as circular, triangular, rectangular, hex...

Wide Band Linear Printed Antenna Array with Low Sidelobe Cosecant Square-shaped Beam Pattern

A wide band, integrated linear printed antenna array with low sidelobe cosecant square-shaped beam pattern is presented. Array synthesis mainly about the wide shaped coverage, low ripple and sidelobe level (SLL) has been done using the modified least square method by matrix inversion. A printed dipole integrated with wideband balun has been chosen as the array element for wide bandwidth and goo...
