Dual-Polarized Patch Antenna-in-Package with High Isolation for Ka-Band 5G Communications
2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)
In this paper we describe the design of a dual polarized packaged patch antenna for 5G communications with improved isolation and bandwidth for Ka-band. The results were validated using FEM and Momentum co-simulations in ADS. The novelty of the approach is the use of parasitic elements in the same layer to circumvent bandwidth limitations, thereby reducing the layer count in contrast to previous designs, combined with a differential feeding technique for improved isolation and radiation pattern stability, albeit at the expense of an increased complexity in the matching process. A peak gain of 5 dBi, isolation above 40 dB and a radiation efficiency of 60% were obtained.

Due to lower latency, greater transmission speed, wider bandwidth, and the possibility to connect with greater multiple devices, fifth-generation (5G) networks are far better than 4G. In this study, a microstrip patch antenna operating at 28 GHz is investigated and modeled for future 5G communication technologies. The substrate used in this work for the antenna is Rogers RT/Duroid5880. Dielectric of the substrate is 2.2 and thickness is 0.3451 mm. CST software is used to simulate the antenna as it is convenient to use. From the simulation, the return loss, gain, radiation efficiency, sidelobe level was found to be-38.348 dB, 8.198dB, 77%, and-18.3 dB respectively. The result found from this simulation is better than the works took place in the past. As a result, it can be utilized as a capable candidate for 5G wireless technology. The results of this proposed antenna are superior to those of existing antennas published in recent scientific journals.

A design of two microstrip antennas with improved isolation and reduction of mutual coupling between them using metamaterial structure is introduced. The technique which is used to reduce the coupling is complementary split ring resonator (CSRR) loaded between the two microstrip patches. The proposed antenna is designed to operate at frequency of 28GHz. This structure is suitable to operate in 5G and mm-wave antenna systems. A significant improvement in coupling between antennas using metamaterial structure is obtained compared to EBG structures at the same frequency. The maximum isolation achieved by etching the CSRR on the ground of the proposed antenna and on a floated ground between the two patched is 36.2 dB. The distance from edgeto-edge of the patch antennas is 0.4λ0. In addition to design and simulate the proposed antenna using CST program, it is also fabricated and measured. Good agreement is achieved between simulated and measured results.
Miniaturized Parasitic Loaded High-Isolation MIMO Antenna for 5G Applications
Sensors
In this paper, a multiple-input–multiple-output (MIMO) antenna is reported for 5G frequency range-2 (FR-2), 28 GHz bands. The MIMO antenna is developed in multiple iterations, including single-element design, cross-polarization reduction, and mutual coupling reduction. Initially, a single-element coplanar edge feed rectangular patch antenna is designed and the E-plane cross-polarization is reduced by −13 dB by trimming the forward corners of the patch. The ground plane is truncated to improve the −3 dB half-power-beamwidth (HPBW). A multi-wavelength spiral inspired parasitic surrounding the single element antenna is loaded, and performance analysis is performed. This parasitic element is used for self-field cancelation for the MIMO configuration. Two MIMO configurations, one with linear and the second with inverted elements, are developed and investigated. The first configuration is found to have better isolation of less than −25 dB compared to the −20 dB of the second configuration...

A dual-band dual-polarized base station antenna for the fifth-generation (5G) mobile system is presented in this paper. The proposed antenna covers the frequency bands from 3.3 to 3.8 GHz (the lower band) and from 4.8 to 5.0 GHz (the upper band) with good isolation between its ports (≥ 20 dB). It consists of two double-oval-shaped dipoles, two double-oval-shaped feeding lines and a cavity reflector. In this design, parts of the dipole antenna structure are used as the feeding lines and it is found that using one arm of the dipole to feed the whole antenna can improve impedance matching. The dual-band performance is achieved by integrating a small oval-shaped loop within the large oval-shaped loop without increasing the size of the radiating patch. The size of the radiating patch is only 0.26λ 0 × 0.26λ 0 (λ 0 is the free-space wavelength at 3.3 GHz). The cavity reflector improves the gain performance and reduces the overall size of the antenna, which is only 0.66 λ 0 × 0.66λ 0 × 0.2λ 0. The antenna has an average realized gain of 7.56 dBi in the lower band and 7.42 dBi in the higher band. Meanwhile, for both bands, the radiation pattern is stable, and the half power beamwidth is within 65 • ± 5 •. Both simulated and measured results demonstrate that the antenna is a very good candidate for 5G mobile base stations.
