Design of dual ports coplanar waveguide MIMO system for UWB applications

Abstract

In this research, a compact of four elements of dual ports coplanar wave guide (CPW) ending with T-shape stub are installed each one on a corner of 85×134 mm2 printed circuit board (PCB). Each element is connected through the SMA connector “panel mount jack receptacle-2-hole flange-tap terminal”. A twin of opened circular parasitic rings are installed in front of each T-stub. A large number of try and error are applied to select the optimum geometry dimensions of the proposed paradigm. The result of paradigm show that each element operated with a resonance frequency 6.35 GHz, 7.1 GHz is the operating frequency overall system. Also, by utilizing the twin of opened circular parasitic ring, a good isolation is achieved with -48 dB. The obtained band frequency 1.74 (6.64-8.38) GHz are covered an important part of UWB which may be used at a sub band of 5G. In addition, the size of the prototype is suitable for future smartphone applications

A Design of CP-MIMO System with Elements of a Diamond-Ring Slot for 5G Mobile-Phone

“…All elements were accomplished by using the micro-strip feed lines T-shaped with the diamond-ring slot antenna. We proposed a T-shape in this paper to achieve an elevation radiation pattern and good return loss [15]. Designed antenna configuration parameter values are listed in Table 1.…”
