چکیده
Abstract This paper investigates uni-/multi-cast and orbital angular momentum (OAM) mode data transmission in orthogonal directions by the utilization of a new circular antenna array, operating at 28 GHz. In horizontal plane proposed array operates as multimode transmitter (i.e., it provides broad-, uni- and/or multi-cast communication), while vertical direction OAM occurs is capable generating up to 15 spatially modes). Antenna designed using twelve, low-complexity, electromagnetically coupled microstrip patch antennas with high radiation efficiency. Each these can transmit power equivalent order magnitude both broadside pattern) endfire over electromagnetic waves electric components. property leads formation modes direction, respectively. was tested through full-wave analysis measurements terms impedance matching, mutual coupling pattern: good agreement between simulated measurement results observed. Specifically, presents 8.65 dBi 6.48 realized gain under uni-cast (in plane) plane), The perfect candidate for spectral efficiency 5G beyond wireless applications, where orthogonality communication links multiplexing requirement.

متن کاملRearrangeable f-cast multi-log2 N networks
Multi-log2 N networks (or vertically stacked banyan networks) have been an attractive class of switching networks due to their small depth O(log N), absolute signal loss uniformity and good fault tolerance property. Recently, F.K.Hwang extended the study of multi-log2 N networks to the generalf -cast case, which covers the unicast case (f = 1) and multicast case (f = N) as special cases, and de...
