Radial line slot array antenna with broad beam is easily realized at frequencies in the lower part of super high frequency band. But emerging broadband mobile communication systems like the fifth generation target frequencies in the upper part of the band and beyond. Therefore, this paper presents the design of beam broadened radial line slot array antenna at 28 GHz for fifth generation broadband mobile communication system. Surface slot distribution synthesis was carried on beam squinted standard single layer radial line slot array design to achieve the broad beam. Using computer simulation technology microwave studio 2014 software, 85 mm radius antenna having polypropylene (ɛr = 2.33) as cavity material was realized. Simulated results shows a gain of 15.8 dB, impedance bandwidth of 1.6 GHz, radiation efficiency of 96 % and 3 dB half power beamwidth of up to 32.3o.

A compact substrate integrated waveguide (SIW) antenna array that operates at 28 GHz and 38 GHz is proposed for fifth generation (5G) applications. The proposed array consists of four SIW cavities fabricated on one single layer of substrate. Each cavity implements a rhombic slot and a triangular-split-ring slot, resonating on TE101 and TE102 modes at 28 GHz and 38 GHz, respectively. In comparison with dual-band SIW antennas in the literature, the proposed configuration depicts a miniature footprint (28.7 × 30.8 mm2) without stacking substrates. To excite the four cavities with equal power, a broadband power divider that supports the propagation of TE10 mode is designed. Accordingly, the impedance bandwidths are 26.6–28.3 GHz and 36.8–38.9 GHz. The measured realized peak gain over the lower and higher bands is 9.3–10.9 dBi and 8.7–12.1 dBi, respectively. The measured half-power beam widths (HPBWs) at 28 GHz and 38 GHz are 20.7° and 15.0°, respectively. Considering these characteristics, including dual bands, high gain, narrow beam widths, miniaturization, and single layer, the proposed antenna array is a suitable candidate for millimeter-wave 5G communication systems with the flexibility in switching operating frequency bands against channel quality variations.

Large Bandwidth

Mobile broadband communication systems like the fifth generation (5G) will require large bandwidth allocation. Currently, the sweet spot is congested with no enough spectrum to support higher bandwidth allocation. The millimeter wave band is being explored to provide the needed spectrum with 28 GHz so far identified as a potential carrier frequency. Development of complimentary antennas for transmission and reception on the band therefore become necessary. This paper present the design of linearly polarized radial line slot array antenna at 28 GHz for mobile broadband communication system application. The antenna consists of radiating surface with radius ρ sitting on squared cavity and ground of side 2ρ. It is excited via a rear center mounted modified straight dielectric coated 50 Ω SSMA connector. The cavity is filled with layers of air space, low dielectric constant syntactic foam and high frequency laminate RT/duroid 5880. With ρ = 50 mm and a maximum total cavity height of 3.0 mm, the antenna was simulated using Computer Simulation Technology Microwave Studio 2014 software. A gain of 18.13 dB, directivity of 18.4 dBi, efficiency of 96 % and impedance bandwidth of up to 2.34 GHz were realized.

This paper presents a design of a triangular slot-loaded planar rectangular antenna array for wideband millimeter-wave (mm-wave) 5G communication systems. The proposed array realizes an overall size of 35.5 × 14.85 mm2. To excite the array elements, a four-way broadband corporate feeding network was designed and analyzed. The proposed array offered a measured impedance bandwidth in two different frequency ranges, i.e., from 23 to 24.6 GHz and from 26 to 45 GHz. The single-antenna element of the array consists of a rectangular patch radiator with a triangular slot. The partial ground plane was used at the bottom side of the substrate to obtain a wide impedance bandwidth. The peak gain in the proposed array is ≈12 dBi with a radiation efficiency of >90%. Furthermore, the array gives a half-power beamwidth (HPBW) of as low as 12.5°. The proposed array has been fabricated and measured, and it has been observed that the measured results are in agreement with the simulated data.

5G Mobile Communication

As a convenient and efficient public transport system, high speed railway (HSR) was rapidly deployed in China. Since the fifth generation (5G) mobile communication system is commercially applied, it is necessary for mobile terminals antennas to cover multiple operating bands to be compatible with various communication systems. Here a HSR-mounted broadband and high-gain monopole antenna is proposed. By using the meander technology and introducing the tapered structure, the proposed antenna operates over a bandwidth of 694-960 MHz and 1350-5975 MHz (VSWR<1.8), which covers both 2G-5G mobile communication and WiFi frequency bands. The dimensions of the proposed antenna are 400 mm × 330 mm × 78 mm. The measured average gain is 6.11 dBi over the entire bandwidth.

Abstract A wideband circularly polarized (CP) array antenna has significant importance in modern communication system. In this paper, we proposed a wide band CP array by combing dual split ring resonators (DSRRs) to dual layer microstrip antenna. A 2 × 2 dual-layer microstrip antenna array is used to radiate wide band linearly polarized wave, and the 3 × 3 four-layer DSRRs is used as an external polarizer which converts linearly polarized wave to circularly polarized wave at distinct frequencies. The proposed array achieves an impedance bandwidth of 20% ranging from 4.57–5.57 GHz and AR bandwidth of 16.83% ranging from 4.57–5.41 GHz. The prominent futures of the proposed array are wide impedance bandwidth on desired frequencies. This new concept is theoretically and experimentally investigated to evaluate the performance of the proposed array, which allows a better prospect for the application of radar and satellite communication systems.
