“…To achieve this goal, the important of milimeter wave frequencies seems to be inescapable because of the large of spectrum that could be mace accessible for that reason [2]. From these milimeter wave bands, the 28 GHz particular interest defined from Ka band as frequencies range 26.5-40 GHz [2] and now low cost antenna are being research and developed [6] [7][8] [9][10] [11] [12]. The 28 GHz band is currently available spectrum over 1 GHz of bandwidth [13], and also directions has just begun moving to empower outdoor operation [2].…”

Recently, the industry and academia there is significant activity in research and development towards the next generation micro and Pico cellular wireless Networks (5th generation). This paper presents, a structure design of microstrip patch antenna array operate at the central frequency of 28 GHz waveband is proposed. The patch antenna array consists of four elements with rectangular patch and uniform distribution. It has a compact size of 26.51 x 20.37 mm with operating frequency at 28 GHz. The inset feed technique is used for the matching between radiating patch and the 50Ω microstrip feedline. The proposed 2x2 antenna array successfully improve the antenna gain up to 8.393dB compare to existing CRLH TL CPW antenna with 2.99 dB, wideband antenna with 7.1 dB and 3.7 dB for broadband elliptical-shaped slot antenna. As a conclusion, the directivity of 10.13 db and efficiency is higher than 80% considered as a potential candidate for the 5G wireless networks and applications.

In this paper, design and analysis of a millimeter wave dual-and dual-polarized antenna for 5G millimeter communications system is presented. The proposed design has a compact structure with size of 5×5 mm 2 . It consists of a rectangular patch with a crossed-slot etched off in the patch to reduce the interference between the two targeted 5G bands of 28 and 38 GHz. To achieve dual polarization performance, the radiating patch is fed by two different 50-Ω microstrip transmission lines. The antenna has -10dB impedance bandwidths of 2.6GHz (26.8-29.4 GHz) and 2.5GHz (37.7-40.2GHz) to cover 28/38 GHz mobile communication bands respectively. The antenna has the merits of miniaturized dimensions, stable broadside radiation patterns with high gains and low cross polarization in both bands of operation. Keywords-Fifth generation (5G), polarization diversity, orthogonal polarization, cross polarization, front to back ratio (FBR).I.

A compact planar inverted-F antenna (PIFA) with single layer dielectric load is presented in this paper. The proposed antenna covers 28 GHz millimeter wave frequency bands and can be useful for future 5G hand held devices. The antenna is placed on a mobile phone substrate of dimensions 110 mm × 60 mm reserving 70 mm × 35 mm for a battery, and occupies a small volume of 4 mm × 4 mm × 1.34 mm. The antenna has a wide operating bandwidth (|S11| < −10dB) of 980 MHz (27.47 − 28.45 GHz) and a peak gain of 8.80 dBi with a gain variation of less than 0.55 dB within the antenna bandwidth. The proposed antenna has stable broadside radiation in yz and xz planes with low side lobe levels of -13.3 dB, -14.4 dB, and wide beamwidths of 66.6 • , 64.5 • , respectively. Radiation efficiency and total efficiency of the antenna vary between 97% − 99% and 88% − 96%, respectively. Antennas impedance bandwidth, gain, radiation, and total efficiency are assessed with and without a battery.Index Terms-28 GHz band, millimeter-wave communications, 5G mobile device, PIFA.
