Orthogonal Printed Microstrip Antenna Arrays for 5G Millimeter-Wave Applications

Abstract

This article presents the design of a planar MIMO (Multiple Inputs Multiple Outputs) antenna comprised of two sets orthogonally placed 1 × 12 linear antenna arrays for 5G millimeter wave (mmWave) applications. The arrays are made of probe-fed microstrip patch antenna elements on a 90 × 160 mm2 Rogers RT/Duroid 5880 grounded dielectric substrate. The antenna demonstrates S11 = −10 dB impedance bandwidth in the following 5G frequency band: 24.25–27.50 GHz. The scattering parameters of the antenna were computed by electromagnetic simulation tools, Ansys HFSS and CST Microwave Studio, and were further verified by the measured results of a fabricated prototype. To achieve a gain of 12 dBi or better over a scanning range of +/−45° from broadside, the Dolph-Tschebyscheff excitation weighting and optimum spacing are used. Different antenna parameters, such as correlation coefficient, port isolation, and 2D and 3D radiation patterns, are investigated to determine the effectiveness of this antenna for MIMO operation, which will be very useful for mmWave cellphone applications in 5G bands.

Multi-slot Antennas Excited by Novel Dual-stub Loaded Microstrip Lines for 4G/5G Bands

“…Remarkably, this antenna covers the newly released 5G new radio (NR) frequency bands: n77 to n79 frequency bands, beyond the 4G/LTE frequencies. [25][26][27][28] discuss several antenna designs for these newly allocated frequency bands for 5G NR bands where PIFA-based or printed designs are incorporated with array antennas to accommodate the new bands. This extended frequency coverage of both the 4G and 5G NR bands makes this proposed antenna very desirable in the case of switching between 4G and 5G systems as more mobile operators deploy new 5G wireless systems, and existing 4G/LTE systems are still in operation.…”

A miniaturized mm‐wave leaky wave antenna based on CRLH slow‐wave SIW for symmetric wide angle beam scanning

“…Kandwal et al have proposed a low‐profile LWA using a bending technique for wideband beam scanning in Ku‐band with a peak gain of 14 dBi 14 . Similarly, several SIW LWAs are presented including high gain LWA with backward scanning, 15 resonant cavity LWA Structure for 5G applications, 16 circularly polarized LWA, 17 compact omnidirectional LWA, 18 asymmetrical SIW‐based LWA with continuous beam scanning, 19 LWA with beam scanning from backfire using odd‐mode spoof surface plasmon polaritons, 20 Archimedean spiral slotted LWA, 21 and orthogonal printed microstrip antenna arrays for 5G Millimeter‐Wave beam scanning application 22 …”

However, in many applications, a compact LWA with high radiation efficiency and reduced size is preferred.…”

Coding Metamaterial Analysis Based on 1-Bit Conventional and Cuboid Design Structures for Microwave Applications

“…Hence, this study adopted only six square-shaped metamaterial rings designed on a Rogers RO3006 substrate material with a thickness of 0.25 mm. On the other hand, Hossain et al introduced a planar multiple-inputs multiple-outputs (MIMO) antenna consisting of two sets of orthogonally placed 1 × 12 linear antenna arrays for 5G millimetre wave applications in 2021 [ 13 ]. A 90 mm × 160 mm Rogers RT/Duroid 5880 grounded substrate material was adopted in this work.…”
