A compact 2×2 dual-band MIMO antenna is proposed with polarization diversity technique for present wireless applications. The proposed design combines the horizontally and vertically polarized radiating elements. The effect of mutual coupling between radiating elements is reduced by partially stepped ground (PSG) and by the orthogonal placement of antenna elements. The whole configuration is de...

Abstract—In this paper, a printed slot antenna fed by a co-planar waveguide for ultra wide bandwidth (UWB) with dual notch bands has been presented and discussed. The band notches are realized by etching one C-slot resonator inside a plaque shape exciting stub as well as symmetrically adding a pair of open-circuit stubs at the edge of the slot resulting in dual stop band filtering properties fo...

A meander metamaterial line (metaline) antenna, which consists of P- and C-type meta-atoms, is investigated to form a circularly polarized (CP) broadside beam across two frequency bands. The antenna has an extremely low-profile flat structure approximately 0.01 wavelength small area less than 0.5 × at the low design frequency. It found that proposed operates dual wider bands compared with those...

This paper presents a design and performance analysis of 10-element 5G massive Multiple Input Output (m-MIMO) antenna array for sub-6 GHz mobile handsets, specifically Long Term Evolution (LTE) bands 43 (3600–3800 MHz) 48/49 (3550–3700 applications. The proposed consists ten closely spaced inverted-F antennas with compact size 20 × 9 mm2 single element. provides high efficiency low correlation ...

This communication defines a figure of merit for multiband antennas that gives an objective quantification of the similarities between radiation patterns at the different antenna operating bands.
