In this article, a compact millimeter wave massive MIMO dual-band (28/38 GHz) antenna array for future 5G communication systems is proposed. A compact high gain dual-band (28/38) series fed antenna array with size of (13× 20 mm2) is nominated to design the massive MIMO antenna system. The simulated results shows that the impedance bandwidth (S11< −10 dB) is achieved around 28 GHz and 38 GHz with...
In this paper, an UWB high gain fermi taper slot antenna for 5G mobile communication networks is proposed. The antenna has a compact volume of 16.1 × 10 × 0.127 mm3. The matching between a rectangular taper slot and 50-Ω microstrip line is manipulated through aproximity-feed technique. Furthermore, the fermi taper slot antenna is modified by incorporating corrugations on the edges of fermi metallic...
In this paper, a broadband elliptical-shaped slot antenna for the future fifth generation (5G) wireless applications is proposed. The antenna has a compact size of 0.5λ0 × 0.5λ0 at 30 GHz. It consists of a circular shaped radiating patch fed by a 50-Ω microstrip line via proximity-feed technique. An elliptically shaped slot is etched in the ground plane to enhance the antenna bandwidth. A stub has...
A design and analysis of a 28/38 GHz dual-band CPW slot directive antenna are presented. To obtain a dual band at 28/38 GHz that covers 5G applications, chambered rectangular patches are printed on a low permittivity “εr2=2.2” grounded substrates with a 0.254-mm-thick where it is fed by a 50Ω microstrip line on the backside through a staircase rectangular apertures etched in the ground plane. The...
A design and analysis of a proximity-fed printed slot antenna with 28/38 GHz dual band characteristics for future 5G wireless applications are presented. To obtain a dual-band at 28/38 GHz that covers 5G applications, an elliptical patch is etched non-concentrically inside a ground plane elliptical slot. The antenna is proximity-fed by a microstrip on the other side of the substrate. Results indicate...
In this article, a dual-band printed slot antenna for the future fifth generation (5G) mobile networks are proposed. The antenna is compact with size of 0.8 λ0 × 0.75 λ0 at 28 GHz. Matching between a sector-disk shaped radiating patch and the 50-Ω microstrip line is manipulated through aproximity-feed technique. An elliptically shaped aperture is etched in the ground plane to enhance the antenna bandwidth...
In this article, a four-element dual-band printed slot antenna array for the future fifth generation (5G) mobile networks is proposed. The antenna element has a compact with size of 0.8 λ0 × 0.75 λ0 at 28 GHz. The simulated results show that the designed antenna has a dual-band function at 28/38 GHz that covers future 5G applications. The designed 1-to-4 modified Wilkinson power divider is used to...
The future mobile network called "5G" is becoming a hot topic. The heterogeneous networks using multi-band "HetNet" is one of the promising candidates which provide more than 1000 times system capacity. Millimeter-wave is expected to be utilized for the pico cell coverage as well as the fronthaul to connect these enhanced RRHs. This paper reviews the antennas and propagation research...
