An ultra-wideband (UWB) millimeter-wave (mm-Wave) dipole antenna array for fifth generation (5G) communications is presented in this paper. The proposed antenna is working in the frequency range of 23-33 GHz (10 GHz bandwidth with more than 35% FBW). Ten compact UWB dipole antenna elements designed on a Rogers RT5880 substrate have been deployed along the edge region of the cell phone PCB. The feature of compact design with UWB characteristic makes them well-suited for 5G cellular devices such as laptops, tablets, mobile phones etc. Input impedance and radiation properties of the proposed antenna array have been discussed. The antenna features quasi-omnidirectional radiation beams at different scanning angles. I.

A New CPW-Fed Diversity Antenna for MIMO 5G Smartphones

et al. 2020

In this study, a new coplanar waveguide (CPW)-fed diversity antenna design is introduced for multiple-input–multiple-output (MIMO) smartphone applications. The diversity antenna is composed of a double-fed CPW-fed antenna with a pair of modified T-ring radiators. The antenna is designed to cover the frequency spectrum of commercial sub-6 GHz 5G communication (3.4–3.8 and 3.8–4.2 GHz). It also provides high isolation, better than −16 dB, without an additional decoupling structure. It offers good potential to be deployed in future smartphones. Therefore, the characteristics and performance of an 8-port 5G smartphone antenna were investigated using four pairs of the proposed diversity antennas. Due to the compact size and also the placement of the elements, the presented CPW-fed smartphone antenna array design occupies a very small part of the smartphone board. Its operation band spans from 3.4 to 4.4 GHz. The simulated results agree well with measured results, and the performance of the smartphone antenna design in the presence of a user is given in this paper as well. The proposed MIMO design provides not only sufficient radiation coverage supporting different sides of the mainboard but also polarization diversity.

“…Then, in [9] a low profile antenna has been proposed with the scan angle of ±80°. Finally, in [14] the wide scan antenna array with the scan angle of over ±85°has been proposed. However, all of those phased array designs have a narrow band characteristics or require big clearance to achieve wide scan angles.…”

In this paper a quad-mode endfire planar phased antenna array with wide scan angle and 1.2 mm clearance is proposed for 5G mobile terminals. The proposed antenna can obtain over 8 GHz of impedance bandwidth. Here is suggested to efficiently combine a multi-mode array element with different radiation patterns for each mode into a phased antenna array. In the array, similar and wide embedded radiation patterns are obtained for the all four modes. Furthermore, a coaxial to differential stripline transition is designed in this work. The differential feeding structure is very compact and utilizes only MMPX connector and vias. The total scan pattern and coverage efficiency of the measured and simulated phased array antenna are calculated in the range from 25 to 33 GHz, and a good agreement between measured and simulated results is observed. The mean coverage efficiency along the frequency range is very similar, but minor difference in variance of coverage efficiency is observed in the measurements. The coverage efficiency of around 50 % for the threshold gain of 5 dBi is achieved in the chosen frequency range.
